LIST PRICES, WEIGHTS, SPECIFICATIONS, GENERAL INFORMATION 1920 Joseph T. Ryerson & Son 'CI.A56688a *vo | .-^s THIS BOOK has been compiled with a view toward giving the trade a convenient handbook of tables and information frequently required during the day's routine business. THE INDEX in the front of the book has been made as complete as possible. The character of the sub- ject matter, however, makes it im- possible to index every item of in- formation given without making the index almost as large as the book itself. To facilitate ready reference, we have also provided a thumb index and have classified the subject matter under the following headings : Section I — Prices and Extras Section II — Weights Section III — Standard Specifications Section IV — General Data We want this book to be of real service to you. Perhaps there are other tables or information which you require daily but which are not contained in this book. If so, we will be glad to send them to you and, if possible, include them in the next issue of this book. Joseph T.Ryersqn&Son CHICAGO ST. LOUIS DETROIT BUFFALO NEW YORK Copyright, 1920 Joseph T.

CUTTING EXTRAS Cutting to lengths 3 ft. and over No extra Cutting to lengths under 3 ft. down to 2 ft., inclusive $0.25 Cutting to lengths under 2 ft. down to 1 ft., inclusive 50 Cutting to lengths under 1 ft 1.55 REGULAR SKETCHES With not more than four straight cuts, including straight, taper plates, length 3 ft. and over $0.10 IRREGULAR SKETCHES With more than four straight cuts, length 3 ft. and over . . . $0.20 Sketches cannot be sheared with re-entrant angles. All sketch plates (other than those sheared to a radius) will be invoiced at actual weight of the sketch, at the base price, plus standard card extras (including sketch extras mentioned above), with an additional charge for waste, if any, to be determined by deducting the actual weight of each sketch from the estimated table weight of the smallest rectangular plate from which the said sketch can be secured, the difference being invoiced at the rectangular plate price, less an allowance for the value as scrap, which allowance shall be 40% of the base price of rectangular plate. This 40% is the average ratio between No. 1 Heavy Melting Steel Scrap and finished plate prices in the United States over a period of 15 years. Sketches sheared to a radius take circle extras. NOTE. — The "rectangular plate price" at which the difference is to be invoiced, is held to be the net price f. o. b. Mill, which the maker would have realized had the rectangle been shipped to the same destination as the sketch cut from it. Such price is properly figured by adding to the Pittsburgh base price the full extras for size, gauge, quality and cutting to length, and the carload freight rate from Pittsburgh to destination; and then deducting the carload freight rate from maker's mill to destination. CIRCLES Diameters 3 ft. and over, 25% of base price. Half circles take circle extras. Sketches or circles over 100 in. in width or diameter take width extras in addition to sketch or circle extras. All sketches, regular, irregular, circular, semi-circular or special, with greatest dimension under 3 ft. take cutting to length extras under rectangular plates in addition to sketch or circle extra. Sketches cannot be sheared with re-entrant angles. INSPECTION Charges for other than mill inspection, such as "Lloyd's" or "American Bureau of Shipping," for buyer's account. PRESSING STEEL This is a quality of plate steel made for ordinary hot-pressing, flanging, or bending work. It is preferred that no requirements be specified by the purchaser, but that it shall be left to the manufacturer to furnish a steel which with proper handling will do such work as above specified. This quality is not guaranteed to stand stamping, deep-drawing or cold-flanging. If the purchaser desires to specify a tensile range of not less than 10,000 lbs., he may do so, but thereby assumes responsibility for the working of the steel. This quality is distinct from flange steel for boiler work, which is covered as heretofore. 26 JOSEPH T. RYERSON & SON SHEETS Extras to Be Added to Base Price (Cents per 100 lbs.)

SPOT TEST Determination of coating by spot test is usually conducted by the lead acetate method. It is understood by the galvanizer that the lightest spot on any sheet must not fall below the stipu- lated minimum called for by the specification.

All test pieces shall be selected by the Surveyor and tested in his presence, and he shad satisfy himself that the conditions herein described are fulfilled. 6 — Tensile Tests. Plates. — The tensile breaking strength of steel plates, determined from Standard test pieces, shall be between the limits of 28 and 32 tons per square inch. For plates specially intended for cold flanging and marked for identi- fication, the tensile strength shall be between the limits of 26 and 30 tons per square inch. In the case of material for pur- poses in which tensile strength is not important, the tensile test may be dispensed with and the bend test only be made, if so specified by the builders and approved by the Committee. The elongation, measured on a Standard test piece having a gauge length of 8 inches, shall not be less than 20 per cent for material of .375 inch in thickness and upwards, and not less than 16 per cent for material below .375 inch in thickness. Angles, Bulb Angles, Channels, etc. — The tensile breaking strength of sectional material, such as angles, bulb angles, channels, etc., shall be between the limits of 28 and 33 tons pep square inch. In the case of material for purposes in which 96 JOSEPH T. RYERSON & SON LLOYD'S SPECIFICATIONS— Cont. tensile strength is not important, the tensile test may be dis- pensed with and the bend test only be made, if so specified by the builders and approved by the Committee. The elongation measured on a Standard test piece having a gauge length of 8 inches shall not be less than 20 per cent for material of .375 ^inch in thickness and upwards, and not less than 16 per cent "for material below .375 inch in thickness. Rivet Bars. — The tensile breaking strength of steel rivet bars, when required by the Committee to be tested, shall be between the limits of 25 and 30 tons per square inch of section, with an elongation of not less than 25 per cent of the gauge length of eight times the diameter of the test piece, measured on the Standard test piece B, or 30 per cent measured on the Standard test piece C. The bars may be tested the full size as rolled.

H K When the Surveyor is in constant -attendance at the Steel Works the following requirements are to be complied with: 7 — Number of Tensile Tests. — Plates and Sectional Material. — One tensile test for plates or sectional material shall be taken from the finished material of each charge. When the quantity of the material from one charge exceeds 25 tons, a second tensile test will be required; also additional tests shall be made for every variation in thickness of .15 of an inch in the plates or sectional bars from each charge. Rivet Bars. — When required by the Committee to be tested, one tensile test shall be taken from each charge used for rivet bars; but when the weight of the bars, as rolled, from one charge exceeds 10 tons, an additional tensile test shall be made for each further 10 tons or portion thereof. Should a tensile test piece break outside the middle half of its gauge length, and the elongation be less than that required by the Rules, the test may, at the maker's option, be discarded and another test be made of the same plate or bar. S — Bend Tests. — Cold Bends. — Test pieces shall be sheared lengthwise or crosswise from piates or bars, and shall noi be less than 1 H inches wide, but for small bars the whole section may be used. For rivet bars bend tests are not required. Temper Bends. — The test pieces shall be similar to those used for cold bend tests. For temper bend tests the samples shall be heated to a blood red and quenched in water at a temperature not exceeding 80 degrees Fahrenheit. The color shall be judged indoors in the shade. In all cold bend tests, and in temper bend tests on samples .5 inches in thickness and above, the rough edge or arris caused by shearing may be removed by filing or grinding, and sampies 1 inch in thickness and above may have the edges machined, but the test pieces shall receive no other preparation. The test pieces shall not be annealed unless the material from which they are cut is similarly annealed, in which case the test pieces shall be similarly and simultaneously treated with the material before testing. STEEL FOR IMMEDIATE SHIPMENT 97 LLOYD'S SPECIFICATIONS— Cont. For both cold and temper bends the test pieces shall withstand, without fracture, being doubled over until the internal radius is equal to 114 times the thickness of the test piece, and the sides are parallel. ■ For small sectional material these bend tests may be made from the flattened bar. Bend tests may be made either by pressure or by blows. 9 — Number of Bend Tests. — A cold or temper bend test shall be made from each plate or bar as rolled, and these tests shall be in about equal numbers from each charge; but a cold bend test shall be made from all plates which are specially marked for cold flanging. 10 — Tests for Manufactured Rivets — Rivets selected by the Surveyor from the bulk shall withstand the following tests: (a) The rivet shanks are to be bent cold, and hammered until the two parts of the shank touch in the manner shown in Fig. 1, without fracture on the outside of the bend. (b) The rivet heads are to be flattened, while hot, in the manner shown in Fig. 2, without cracking at the edges. The heads are to be flattened until their diameter is 2 }4 times the diameter of the shank. Fig. 2. 11 — Additional Tests before Rejection. — Should any of the test pieces first selected by the Surveyor not fulfill the test require- ments, two further tests may be made from the same plate or bar, but should either of these fail, the plate or bar from which the test pieces were cut shall be rejected. In all such cases further tests shall be made before any material from the same charge can be accepted. 12 — Branding. — Every plate and bar shall be clearly and dis- tinctly marked by the maker in two places with the Society's brand, thus: indicating that the material has complied with the Society's tests. No plates or bars bearing this brand shall be forwarded from the Steel Works until the prescribed tests have been made by the Surveyor, and the mill sheets have been signed by him. All plates and bars shall also be legibly stamped in two places with the Maker's name or trade mark and the place where made. They shall also be stamped with numbers, or identification marks, by which they can be traced to the charge from which the material was made. 13 — Maker's Certificate. — Before the mill sheets are signed by the Surveyor the Maker shall furnish him with a certificate guaranteeing that the material has been made by the Open Hearth process, and that it has been subjected to, and withstood satisfactorily, the tests above described, in the presence of the Surveyor. The following form of certificate will be accepted if printed on each mill sheet with the name of the firm, and initialled by the Test House Manager. "We hereby certify that the material described below has been made by the Open Hearth process, and is that which has been satisfactorily tested in the presence of the Surveyor in accordance with the Rules of Lloyd's Register." 98 JOSEPH T. RYERSON & SON LLOYD'S SPECIFICATIONS— Cont. 14 — Rejected Material. — In the event of the material failing, in any case, to withstand the prescribed tests, the Surveyor shall see that the Society's brand stamped on the plates and bars by the Maker has been defaced by punch marks extending beyond the brand in the form of a cross, thus : denoting that the material has been rejected. 15 — Facilities for Inspection. — The Maker shall adopt a sys- tem of marking the ingots, billets, slabs, plates, bars, etc., which will enable all finished material to be traced to the original charge, and the Surveyor must be given every facility for tracing all plates and bars to their respective charges, and for witnessing the required tests. When he is satisfied with the material and with the results of the tests, he shall be furnished with two copies of the advice notes of the material for his signature, o,ne of which is to be forwarded by the Manufacturer to the Shipbuilder, and the other is to be forwarded by the Surveyor to the Surveyors at the port where the vessel is to be built. 16 — Steel not Produced Where Rolled. — Where steel is not produced in the works at which it is rolled, a certificate shall be supplied to the Surveyor stating the Open Hearth process by which it was made, the name of the Steel Maker who supplied it, also the numbers of the charges, for reference to the books of the Steel Maker. The number of the charge shall be marked on each ingot or billet for the purpose of identification, and the finished plates and bars shall also be legibly stamped in two places with the maker's name or trade mark and the place where made. They shall also be stamped with numbers or identifica- tion marks by which they can be traced to the charge from which the material was made. 17 — Occasional Attendance at Steel Works. — When the Society's Surveyor is not in constant attendance at the Steel works, the Makers themselves may, with the written authority of the Society, comply with all the foregoing requirements, and shall furnish the Surveyor with a certificate to the effect that the Society's Rules as to the testing of steel have been complied with in the case of the material submitted for approval. The Surveyor shall then make check tensile, cold, and temper bend tests from not less than one plate or bar in every batch of 50 or less number, provided the batch be all from one charge. If more than one charge is represented, each charge shall be tested. Additional tests shall also be made for every variation in thick- ness of .15 of an inch made from one charge. The test pieces shall be selected by the Surveyor from the plates or bars, and not from sheaiings previously detached from them, and when marked by the Surveyor for testing they shall be followed, as far as practicable, through the different stages of preparation until the tests are completed. Should the tests be unsatisfactory, the whole of the material from the charge shall be rejected, and the Surveyor shall see that the Society's brand is satisfactorily defaced. 18 — General. — Besides the foregoing tests, samples of all material may be subjected to additional tests at the discretion of the Surveyors. 19 — In cases wherein it may be desired by Owners and Builders, consideration will be given by the Committee to proposals for the use of steel of othei tenacity than is provided for in the foregoing Rules. STEEL FOR IMMEDIATE SHIPMENT 99 GENERAL DATA DEFINITIONS OF COMMON TERMS Tensile Strength. — (Ultimate or Maximum Stress). Maximum load material can sustain in tension without fracture. Elastic Limit is the maximum stress a material can bear without permanent distortion or set. Within certain limits, steel is an elastic body and on being elongated by a tensile strength, returns to its original dimensions when the force ceases to be applied. Elongation is the increase in length which a metal bar undergoes when subjected to a tensile stress sufficient to cause fracture. Reduction of Area is the amount of contraction of area which takes place at the point of fracture when a metal bar is broken by a direct pulling force. Both the elongation and reduction of area furnish valuable indications of the ductility of steel; the greater they are for the same class of material, the softer and more ductile the material may be considered. Yield Point in ordinary commercial practice is the same as the elastic limit. Red Shortness. — Steel to be free from "red shortness" must be capable of being worked at all temperatures from a red to a welding heat without showing any signs of cracking or other defects. Cold Shortness. — Steel to be free from "cold shortness" must not show any signs of brittleness under sudden shock, or under a steadily applied load in the cold condition, the stress which such steel may reasonably be expected to bear varying with its carbon content. Steel is a chemical compound of iron and carbon; that is, it contains no carbon in a free state as cast iron does. Its tensile strength is greater than that of wrought iron, and its compressive strength greater than that of cast iron. Steel, unlike wrought iron, is fusible; unlike cast iron, it can be forged, and with the exception of the higher grades it can be welded by heating and hammering, although care must be exercised in so doing. Effect of Carbon on Steel. — Increasing the carbon content in- creases the tensile strength, as will be noted from the following table. 'Effect of Sulphur on Steel. — When sulphur is over .06 there is a tendency to red shortness. Numerous cracks are liable to de- velop during rolling, which are imperceptible in the finished material, but which may later form starting points for rupture when material is subject to sudden stress. Free cutting steel, for threading and screw machine work, is ob- tained by increasing sulphur content to about .075 to .10. Effect of Phosphorus on Steel. — Produces brittleness and gen- eral cold shortness. On account of its treacherous nature it may be -stated that the lower the phosphorus, the better the grade of the steel. Effect of Manganese on Steel. — Manganese is added in the making of steel to prevent red shortness and in ordinary grades of steel ranges from about .30 to .60. (When manganese is present in large amount, 7% and over, a GENERAL special steel is produced, possessing great hardness. ^„J^ Effect of Silicon. — In commercial practice the silicon present in steel is very slight and may be considered negligible as affecting the physical properties. 99 100 JOSEPH T.

RYERSON SON NOTES ON CORRUGATED SHEETS TO ASCERTAIN LENGTH OF A CURVED SHEET BY FOLLOWING TABLE Rule. — Divide height (or size) by base (or span), find quotient in column of heights, take length for chat height opposite to it in next column on the right hand. Multiply length thus obtained by base (or span) and product will give length of sheet. Example. — Find length of sheet, base (or span) being 100 inches, rise being 25 inches. 25 divided by 100 equals .25; and .25, per table, equals 1.15912, length of base, which multiplied by 100 equals 115.912 inches, length of sheet before curving.

Short dia. of finished nut = l^Xdia. of bolt+^in. Thickness of rough nut = dia. of bolt. Thickness of finished nut = dia. of bolt+M in- Short dia. of rough head = l^Xdia. of bolt+H in- Short dia. of finished head = l^Xdia. of bolt+Min. Thickness of rough head = A short dia. of head. Thickness of finished head = dia. of bolt+M in. The long diameter of a hexagon nut may be obtained by multiplying the short di- ameter by 1.155 and the long diameter of a square nut by multiplying the short diam- eter by 1.414. The above standards for screw threads, nuts and bolt heads were recommended by the Franklin Institute in De- cember, 1864. The standard for screw threads has been very generally adopted in the United States, but the pro- portions recommended for nuts and bolt heads have not found general acceptance because of the odd sizes of bar — not usual- ly rolled by the mills — re- quired to make the nut.

To find diameter of a circle multiply circumference by .31831. To find area of a circle multiply square of diameter by .7854. Area of rectangle. Length multiplied by breadth. Doubling the diameter of a circle increases its area four times. To find area of a triangle multiply base by Yz perpendicular height. To find surface of a ball multiply square of diameter by 3.1416. To find solidity of a sphere multiply cube of diameter by .5236. To find side of an inscribed square multiply diameter by 0.7071 or multiply circumference by 0.2251 or divide circumference by 4.4428. To find side of an equal square multiply diameter by .8862. Square. A side multiplied by 1.1142 equals diameter of its cir- cumscribing circle. A side multiplied by 4.443 equals circumference of its circumscribing circle. A side multiplied by 1.128 equals diameter of an equal circle. A side multiplied by 3.547 equals circumference of an equal circle. Square inches multiplied by 1.273 equals circle inches of an equal circle. To find cubic inches in a ball multiply cube of diameter by .5236. To find cubic contents of a cone, multiply area of base by X A the altitude. Doubling the diameter of a pipe increases its capacity four times. A gallon of water (U. S. standard) weighs S}i lbs. and contains 231 cubic inches. A cubic foot of water contains 7J4 gallons, 1728 cubic inches, and weighs 62 J^ lbs. To find the pressure in pounds per square inch of a column of water multiply the height of the column in feet by .434. Steam rising from water at its boiling point (212 degrees) has a pressure equal to the atmosphere (14.7 lbs. to the square inch). A standard horse power: The evaporation of 30 lbs. of water per hour from a feed water temperature of 100° F. into steam at 70 lbs. gauge pressure. To find capacity of tanks any size: given dimensions of a cylinder in inches, to find its capacity in U. S. gallons: Square the diameter, multiply by the length and by .0034. To ascertain heating surface in tubular boilers multiply H the cir- cumference of boiler by length of boiler in inches and add to it the area of all the tubes. One-sixth of tensile strength of plate multiplied by thickness of plate and divided by one-half the diameter of boiler gives safe working pressure for tubular boilers. For marine boilers add 20 per cent for drilled holes. To find the capacity of an air compressor in cubic feet of free air per minute: Multiply the area of low pressure cyb'nder (on com- pound compressor), or area of simple compressor cylinder in square inches, by the stroke in inches, and divide by 1728; and multiply this result — (a) In single acting, simple or compound, by the R.

RYERSON & SON TRADE CUSTOMS Quotations All quotations are subject to change without notice, and all sales are made subject to strikes, accidents, or other unavoidable dciiiys. We reserve the right to cancel contracts not fully specified in time agreed upon. Special material is not subject to cancellation without our written consent. Confirmation Orders Confirming orders should be marked Confirmation — preferably across face of order. Confirmation orders not so marked may be treated as original open orders and duplicated — in such cases we will not be responsible for expense and inconvenience incurred. Terms Our terms are one-half of one per cent, for cash in ten days or net cash in thirty days from date of shipment, unless otherwise agreed upon. All payments to be made by bank draft on Chicago or New York, U. S. Treasury notes or their equivalent. Strangers , should accompany their first order with cash or references. Deliveries Material from our warehouse is usually shipped the day order I is received. Orders by telephone are accepted at the risk of the sender, as : shipments made before receipt of confirmation are for the service of the customer. Promises on special work or material from mill are as closely I estimated as possible, and we use our best efforts to ship within the time, but can not guarantee to do so. Clai ms A clear receipt from the railroad places the responsibility for shortage or damage with the carrier, and, if there is any dis- crepancy, your local station agent should be requested to note on the freight bill before it is paid. This will enable you to re- cover on any Legal claim- Carloads are usually forwarded on " Shipper's Load and Count" and should, therefore, be carefully checked while unloading and the railroad agent immediately notified in case of any shortage or damage. Shipments by land, lake or river will be insured only when buyers so instruct — otherwise, we are not responsible for loss or damage, after receiving a clear shipping receipt for the goods. Claims for defective material should be made immediately upon receipt of the goods. Transportation Companies will not accept or pay claims unless filed within six months (freight) or four months (express). Crating "C" Pickled, Extra Deep, Auto Body and Lead Finish Sheets will bfe crated for shipment unless instructed to the contrary. On large orders where we can induce railroad to load carefully in box car without transferring, crating charges can be elimin- ated. Following are charges per crate, based on 500 lbs. or less per crate. Skeleton crates will be used unless otherwise in- structed. Size Skeleton Full All Stock 50 cents per 100 SI. 15 per 100 size sheets lbs. net weight lbs. net weight of sheets of sheets Minimum charge Minimum charge $2.50 $5.75 Packing „ , Boxing is charged on all small or broken lots. Defective Material . All our material and fittings are carefully inspected and our machinery tested before shipment, but in spite of the greatest care it is sometimes impossible to detect all imperfections. We guarantee to replace, with new material, such goods as prove de- fective within a reasonable time, when properly worked or used, but under no circumstances will we be responsible for any dam- ages beyond this. All material claimed defective must be held for our inspection and disposition. No charges for labor or expense required to repair defective goods or occasioned by them will be allowed, the measure of the damages being the price of the defective article. Boiler Construction In the construction of boiler and pressure tanks. Government laws and some State laws, require certain chemical and physical test reports and the stamping of boiler plates, heads and acces- sories with the maker's name and identification marks. If boiler construction material is to comply with any of these specifications, such information should be placed on the order. We can not assume any responsibility other than replacing of material that does not conform to necessary requirements used in the construc- _ tion of any boiler or pressure tank.
