Scope*1.1 This specification covers hot-rolled, heavy-thicknesscoils beyond the size limits of Specification A1011/A1011M.1.2 The product is available in six designations: Commer-cial Steel, Drawing Steel, Structural Steel, High-StrengthLow-Alloy Steel, High-Strength Low-Alloy Ste

5、0, inclFrom 6.0 through 25NOTE 1The changes in width limits with the publication of A635/A635M 06a result in a change in tensile testing direction for materialfrom 0.180 in. 4.5 mm to 0.230 in. exclusive 6.0 mm exclusive over 48in. 1200 mm wide as that material is now covered by SpecificationA568/A5
6、68M 06a. The purchaser is advised to discuss this change withthe supplier.1.4 Sheet and strip in coils of sizes noted in 1.3 are coveredby this specification only with the following provisions:1.4.1 The material is to be fed directly from coils into ablanking press, drawing or forming operation, tub
7、e mill, rollingmill, or sheared or slit into blanks for subsequent drawing orforming.1.4.2 The material is not to be converted into steel plates forstructural or pressure vessel use unless tested in completeaccordance with the appropriate sections of SpecificationsA6/A6M (plates provided from coils)
8、 or A20/A20M (platesproduced from coils). Plate converted from coils is no longergoverned by this sheet steel specification and since thismaterial is now a plate, the requirements of the appropriateplate specification shall apply, except in cases where there is aconflict between the requirements of
9、the plate specification andthis specification. In these cases, the more restrictive limits ofeither specification shall apply.1.4.3 The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specifica-tion.1.4.4 Not all strength levels are available in all thi
10、cknesses.The user should consult the producer for appropriate sizelimitations.1.5 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the
11、other. Combiningvalues from the two systems may result in non-conformancewith the standard.2.
