1.1This 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.

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

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

1.4The 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.

1.5The 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.

1.6The values stated in SI units are to be regarded as the standard.

1.7The 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.

1.8This 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.
