1.1 This specification covers the general requirements for hot-rolled, heavy-thickness sheet and strip in coils.
1.2 It applies to Specification A 1018/A 1018M.
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[over 200 through 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 A 635/A 635M – 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 A 568/A 568M – 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 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 inch-pound units or SI units are to be regarded 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. Combining values from the two systems may result in nonconformance with this specification.
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.
