ASTM A1018/A1018M-03a
(Specification)Specification for Steel, Sheet and Strip, Heavy-Thickness Coils, Hot-Rolled, Carbon, Commercial, Drawing, Structural, High-Strength Low-Alloy, and High-Strength Low-Alloy with Improved Formability
Specification for Steel, Sheet and Strip, Heavy-Thickness Coils, Hot-Rolled, Carbon, Commercial, Drawing, Structural, High-Strength Low-Alloy, and High-Strength Low-Alloy with Improved Formability
SCOPE
1.1 This specification covers hot rolled, heavy thickness coils beyond the size limits of specification A1011.
1.2 The product is available in three designations; Structural Steel, and High-Strength Low-Alloy Steel, Columbium or Vanadium, and High-Strength Low-Alloy Steel with Improved Formability.
1.3 This material is available only in coils described as follows:ProductSize 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
[Over 6.0 to 25]Sheet Over 12 to 48, incl
[Over 300 to 1200] 0.230 to 1.000, incl
[Over 6.0 to 25]Sheet Over 48
[Over 1200]0.180 to 1.000, incl
[Over 4.5 to 25]
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 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 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.
1.4.2 This specification is not applicable to the steels covered by Specification A635/A635M.
1.4.3 The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specification.
1.4.4 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.
1.4.5 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 inch-pound units or SI units [metric] are to be regarded separately as standard. Within the text the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
