Abstract
This specification covers the general requirements for hot-rolled, heavy-thickness, and high-strength low-alloy with improved formability sheet and strip coils. These coils are normally produced from rimmed, capped, or semi-killed steel. Steels may be produced as ingot-cast or strand-cast. Cast or heat analysis shall be made to determine the conformance with the requirements. For steels other than non-killed (capped or rimmed), product analysis may be made. The chemical analysis shall conform to the specified amounts of carbon, manganese, phosphorus, sulfur, silicon, and copper. Steels may or may not be subjected to tension test requirement. Specimen preparation and test methods are discussed. The mechanical property requirements, number of specimens, test locations, and specimen orientation shall be in accordance with the applicable product specification. Tolerances for the dimensions of sheet and strip coils are specified.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers the general requirements for hot-rolled, heavy-thickness sheet and strip in coils.
1.2 It applies to Specifications A414/A414M, A424/A424M, and A1018/A1018M.
1.3 This material is available only in coils described as follows:
|
| Size Limits, Coils Only | |
|
|
|
|
| Product | Width, in. [mm] | Thickness, in. [mm] |
|
|
|
|
| Strip | over 8 to 12, incl | 0.230 to 1.000, incl |
| Sheet | All WidthsA | 0.230 to 1.000, incl |
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 In case of any conflict in requirements, the requirements of the individual material specification shall prevail over those of this general specification.
1.5 Annex A1 lists permissible variations in dimensions and mass (see Note 2) in SI [metric] units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Conformance to Annex A1 is mandatory when the “M” specification is used.
Note 2: The term weight is used when inch-pound units are the standard. However, under SI, the preferred term is mass.
1.6 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.
1.7 This specification and the applicable material specifications are expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
