    ASTM A924 / A924M

    1. Scope

    1.1 This specification covers the general requirements that, unless otherwise specified in the product specification, apply to steel sheet in coils and cut lengths, metallic-coated on continuous lines by the hot-dip process. The product is intended for applications requiring corrosion resistance. The product specifications contain requirements for specific strength levels, heat resistance, paintability, or formability, or a combination thereof.

    1.2 Subject to individual product specification provisions, steel sheet is available as Commercial Steel (CS) Types A, B, and C, Forming Steel (FS), Drawing Steel (DS), Deep Drawing Steel (DDS), Extra Deep Drawing Steel (EDDS), High Temperature Steel (HTS), Structural Steel (SS), and High Strength Low Alloy Steel (HSLAS). Steel sheet is produced with the following metallic coatings. Specific information on each of the following is contained in the individual product specification:

    1.2.1 Zinc or zinc-iron alloy coated,

    1.2.2 Zinc-5 % aluminum alloy coated,

    1.2.3 55 % aluminumzinc alloy coated,

    1.2.4 Aluminumcoated,

    1.2.5 Terne (lead-tin alloy) coated, and

    1.2.6 Zinc-aluminum-magnesium alloy coated.

    1.3 Products covered by this general requirements specification are described in the following product standards: Specifications A308/A308M; A463/A463M; A653/A653M; A755/A755M; A792/A792M; A875/A875M; A929/A929M; and A1046/A1046M.
