This specification deals with the hot-rolled, heavy thickness coils available for three designations: alloy steel, drawing steel, and structural alloy steel. Alloy steel is intended for general or miscellaneous use where bending and moderate forming is required. Drawing steel is used for severe cold plastic deformation such as deep drawn or severely formed parts. The material is available only in coils such as strip and sheet. As-rolled and annealed heat treatment shall be used for manufacturing the material. Drawing steel shall be furnished with a spheroidized annealed heat treatment unless otherwise specified. Heat analysis shall conform to the required grade specified for standard alloy steel, nonstandard alloy steel, and structural alloy steel. Grades shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, and vanadium. Mechanical tests for regular quality alloy steel and strip are not applicable; but for drawing steel and structural alloy steel, tension and hardness tests are required.1.1 This specification covers hot-rolled, heavy thickness coils beyond the size limits of Specifications A506 and A507.1.2 The product is available in three designations: Alloy Steel, Drawing Steel, and Structural Alloy Steel.1.3 Alloy steel is furnished to chemical composition requirements and is intended primarily for general or miscellaneous use where bending and moderate forming is a requirement.1.4 Drawing steel is produced principally for applications involving severe cold plastic deformation such as deep drawn or severely formed parts.1.4.1 Drawing steel may be furnished in several conditions, heat treatments, surface finishes, and edges, as specified herein.1.5 Structural steel is furnished to chemical composition requirements and to specific mechanical property requirements which may include tension tests, hardness tests, or other commonly accepted mechanical tests.1.5.1 The formability of structural steel decreases with increasing yield strength or hardness. Therefore, product design in relation to the mechanical properties of the grade used must be considered.1.6 This material is available only in coils described as follows:Product Size Limits, Coils OnlyWidth, in. [mm] Thickness, in. [mm]Strip Over 8 to 12, incl 0.230 to 1.000, incl  [Over 200 to 300] [Over 6.0 to 25]Sheet Over 12 0.230 to 1.000, incl  [Over 300] [from 6.0 through 25]1.7 Sheet and strip in coils of sizes noted in 1.6 are covered by this specification only with the following provisions:1.7.1 The material is not to be converted into steel plates for structural or pressure vessel use unless tested in complete accordance with the appropriate sections of Specifications A6/A6M (plates provided from coils) or A20/A20M (plates produced from coils). A plate produced in this manner is no longer governed by this sheet steel specification and since this material is now plate, the appropriate plate standard must now apply.1.7.2 The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specification.1.7.3 The material is to be fed directly from coils into a blanking press, drawing or forming operation, tube mill, rolling mill, or sheared or slit into blanks for subsequent drawing or forming.1.8 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.TABLE 1 Standard Steels Commonly Produced for Alloy Steel Sheet and StripSteelDesignationNo. Chemical Composition Ranges and Limits, % (Heat Analysis)A  C Mn P S SiB Ni Cr Mo VE3310C 0.08-0.13 0.45-0.60 0.025 0.025 0.15-0.30 3.25-3.75 1.40-1.75 . . . . . .4012C 0.09-0.14 0.75-1.00 0.025 0.025 0.15-0.30 . . . . . . 0.15-0.25 . . .4118 0.18-0.23 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.40-0.60 0.08-0.15 . . .4130 0.28–0.33 0.40–0.60 0.025 0.025 0.15-0.30 . . . 0.80–1.10 015–0.25 . . .4135 0.33-0.38 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4137 0.35-0.40 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4140 0.38–0.43 0.75–1.00 0.025 0.025 0.15-0.30 . . . 0.80–1.10 0.15-0.25 . . .4142 0.40-0.45 0.75-1.00 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4145 0.43-0.48 0.75-1.00 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4147C 0.45-0.50 0.75-1.00 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4150 0.48-0.53 0.75-1.00 0.025 0.025 0.15-0.30 . . . 0.80-1.10 0.15-0.25 . . .4320 0.17-0.22 0.45-0.65 0.025 0.025 0.15-0.30 1.65-2.00 0.40-0.60 0.20-0.30 . . .4340 0.38–0.43 0.60–0.80 0.025 0.025 0.15-0.30 1.65-2.00 0.70–0.90 0.20-0.30 . . .E4340 0.38-0.43 0.65-0.85 0.025 0.025 0.15-0.30 1.65-2.00 0.70-0.90 0.20-0.30 . . .4520C 0.18-0.23 0.45-0.65 0.025 0.025 0.15-0.30 . . . . . . 0.45-0.60 . . .4615 0.13-0.18 0.45-0.65 0.025 0.025 0.15-0.30 1.65-2.00 . . . 0.20-0.30 . . .4620 0.17-0.22 0.45-0.65 0.025 0.025 0.15-0.30 1.65-2.00 . . . 0.20-0.30 . . .4718 0.16-0.21 0.70-0.90 0.025 0.025 0.15-0.30 0.90-1.20 0.35-0.55 0.30-0.40 . . .4815 0.13-0.18 0.40-0.60 0.025 0.025 0.15-0.30 3.25-3.75 . . . 0.20-0.30 . . .4820 0.18-0.23 0.50-0.70 0.025 0.025 0.15-0.30 3.25-3.75 . . . 0.20-0.30 . . .5015 0.12-0.17 0.30-0.50 0.025 0.025 0.15-0.30 . . . 0.30-0.50 . . . . . .5046 0.43-0.50 0.75-1.00 0.025 0.025 0.15-0.30 . . . 0.20-0.35 . . . . . .5115 0.13-0.18 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.70-0.90 . . . . . .5120 0.17–0.22 0.70–0.90 0.025 0.025 0.15-0.30 . . . 0.70–0.90 . . . . . .5130 0.28–0.33 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.80-1.10 . . . . . .5132 0.30–0.35 0.60-0.80 0.025 0.025 0.15-0.30 . . . 0.75-1.00 . . . . . .5140 0.38–0.43 0.70–0.90 0.025 0.025 0.15-0.30 . . . 0.70–0.90 . . . . . .5150 0.48–0.53 0.70–0.90 0.025 0.025 0.15-0.30 . . . 0.70–0.90 . . . . . .5160 0.56–0.64 0.75–1.00 0.025 0.025 0.15-0.30 . . . 0.70–0.90 . . . . . .E51100C 0.95–1.10 0.25-0.45 0.025 0.025 0.15-0.30 . . . 0.90-1.15 . . . . . .E52100 0.98–1.10 0.25-0.45 0.025 0.025 0.15-0.30 . . . 1.30-1.60 . . . . . .6150 0.48–0.53 0.70-0.90 0.025 0.025 0.15-0.30 . . . 0.80-1.10 . . . 0.15 min6158C 0.55–0.62 0.70–1.10 0.025 0.025 0.15-0.30 . . . 0.90–1.20 . . . 0.10–0.208615 0.13–0.18 0.70–0.90 0.025 0.025 0.15-0.30 0.40–0.70 0.40–0.60 0.15–0.25 . . .8617 0.15–0.20 0.70-0.90 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8620 0.18–0.23 0.70–0.90 0.035 0.035 0.15-0.30 0.40-0.70 0.40–0.60 0.15–.025 . . .8630 0.28–0.33 0.70-0.90 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8640 0.38–0.43 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8642C 0.40-0.45 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8645 0.43-0.48 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8650C 0.48-0.53 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8655 0.501-0.59 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8660 0.55-0.65 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.15-0.25 . . .8720 0.18-0.23 0.70-0.90 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.20-0.30 . . .8735C 0.33-0.38 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.20-0.30 . . .8740C 0.38-0.43 0.75-1.00 0.025 0.025 0.15-0.30 0.40-0.70 0.40-0.60 0.20-0.30 . . .9260 0.56-0.64 0.75-1.00 0.025 0.025 1.80-2.20 . . . . . . . . . . . .9262C 0.55-0.65 0.75-1.00 0.025 0.025 1.80-2.20 . .  0.25-0.40 . . . . . .E9310C 0.08-0.13 0.45-0.65 0.025 0.025 0.20-0.35 3.30-35.0 1.00-1.40 0.08-0.15 . . .(A) The chemical ranges and limits shown are subject to product analysis tolerances.

This specification covers standards for hot-rolled, heavy-thickness steel sheet and strip coils. The materials shall come in the following designations: (a) Commercial Steel (or CS) of Types A and B, and Standard Steel Designation; (b) Drawing Steel (DS) of Types A and B, and Standard Steel Designation; (c) Structural Steel (SS) of Grades 30[205], 33[230], 36[250] in Types 1 and 2, and 40[275]; (d) High-Strength Low-Alloy Steel (HSLAS) of Grades 45[310], 50[340], 55[380], 60[410], 65[450], and 70[480] in Classes 1 and 2; (e) High-Strength Low-Alloy Steel with Improved Formability (HSLAS-F) of Grades 50[340], 60[410], 70[480], and 80[550]; and (f) Ultra-High Strength Steel (UHSS) of Grades 90[620] and 100[690], Types 1 and 2. The strip and sheet coils shall conform to specified limit in width and thickness. Carbon, manganese, phosphorus, silicon, aluminum, silicon, copper, nickel, chromium, molybdenum, columbium, titanium, nitrogen, and boron contents shall be followed as specified by each designations, classes, types, and grades. Tension tests shall be performed. Materials shall adhere to yield strength, tensile strength, and elongation requirements. Guidelines for workmanship, finish, and appearance are given.1.1 This specification covers hot-rolled, heavy-thickness coils beyond the size limits of Specification A1011/A1011M.1.2 The product is available in six designations: Commercial Steel, Drawing Steel, Structural Steel, High-Strength Low-Alloy Steel, High-Strength Low-Alloy Steel with Improved Formability, and Ultra-High Strength Steel.1.3 This material is available only in coils described as follows:Product Size Limits, Coils Only  Width, in. [mm] Thickness, in. [mm]Strip Over 8 to 12, incl[Over 200 to 300] 0.230 to 1.000, incl[From 6.0 through 25]Sheet Over 12[Over 300] 0.230 to 1.000, incl[From 6.0 through 25]NOTE 1: The changes in width limits with the publication of A635/A635M – 06a result in a change in tensile testing direction for material from 0.180 in. [4.5 mm] to 0.230 in. exclusive [6.0 mm exclusive] over 48 in. [1200 mm] wide as that material is now covered by Specification A568/A568M – 06a. The purchaser is advised to discuss this change with the supplier.1.4 Sheet and strip in coils of sizes noted in 1.3 are covered by this specification only with the following provisions:1.4.1 The material is to be fed directly from coils into a blanking press, drawing or forming operation, tube mill, rolling mill, or sheared or slit into blanks for subsequent drawing or forming.1.4.2 The material is not to be converted into steel plates for structural or pressure vessel use unless tested in complete accordance with the appropriate sections of Specifications A6/A6M (plates provided from coils) or A20/A20M (plates produced from coils). Plate converted from coils is no longer governed by this sheet steel specification and since this material is now a plate, the requirements of the appropriate plate specification shall apply, except in cases where there is a conflict between the requirements of the plate specification and this specification. In these cases, the more restrictive limits of either specification shall apply.1.4.3 The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specification.1.4.4 Not all strength levels are available in all thicknesses. The user should consult the producer for appropriate size limitations.1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
