This specification covers steel sheet, complex phase grade, dual phase grade, and transformation induced plasticity grade, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process in coils and cut lengths. The product is produced in various zinc or zinc-iron alloy-coating masses or coating designations. Zinc-coated or zinc-iron alloy-coated sheet in coils and cut lengths is produced to thickness requirements expressed to 0.01 mm. The thickness of the sheet includes both the base metal and the coating. Mechanical property tests shall be conducted in accordance with the methods specified in Specification A924/A924M, or those prescribed by the purchaser. Coating mass tests shall be performed in accordance with the requirements of Speci?cation A924/A924M.

Scope

1.1 This specification covers steel sheet, complex phase (CP) grade, dual phase (DP) grade, and transformation induced plasticity (TRIP) grade, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process in coils and cut lengths.

1.2 The product is produced in various zinc or zinc-iron alloy-coating masses or coating designations as shown in Table 1.

1.3 Product furnished under this specification shall conform to the applicable requirements of the latest issue of Specification A924/A924M, unless otherwise provided herein.

1.4 The product is available in a number of designations and grades with mandatory chemical requirements and mandatory mechanical properties that are achieved through thermal or thermal-mechanical treatments, and are designed to be compatible with automotive application requirements.

1.5 The grade designation nomenclature of the product differs from other hot-dip sheet products having mandatory mechanical properties in that ordering is to tensile, rather than yield strength values.

1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this specification.

1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
