This specification covers steel sheet in coils and cut lengths coated with zinc-aluminum-magnesium alloy by hot-dip process intended for applications requiring corrosion resistance and paintability. The steel sheet shall be produced in the following designations: commercial steel (CS types A,B,C), forming steel (FS type A and B), deep drawing steel (DDS), extra deep drawing steel (EDDS), structural steel (SS), high strength low alloy steel (HSLAS), and high strength low alloy steel with improved formability (HSLAS-F). Structural steel and high strength low alloy steel shall be available in several grades based on mechanical properties such as yield strength, tensile strength, and elongation. Structural steel Grade 50 [340] shall be available in four classes based on tensile strength. The coating weights [masses] shall conform to the specified requirements determined by triple-spot and single-spot tests. The coating bath composition and the method of estimating the coating thickness from the coating weight [mass] are given. Heat analysis of the base metal shall conform to the chemical requirements prescribed for carbon, manganese, phosphorous, sulfur, aluminum, copper, nickel, chromium, molybdenum, vanadium, columbium, and titanium. Bending properties of the base metal including minimum cold bending radii and cracks, and the coating bend test requirements are detailed.

ORDER

Scope

1.1 This specification covers zinc-aluminum-magnesium alloy-coated steel sheet in coils and cut lengths.

1.2 This product is intended for applications requiring corrosion resistance and paintability.

1.3 The steel sheet is produced in a number of designations, types, grades and classes designed to be compatible with differing application requirements.

1.4 Product furnished under this specification shall conform to the applicable requirements of the latest issue of Specification A 924/A 924M, unless otherwise provided herein.

1.5 This specification is applicable to orders in either inch-pound units (as A 1046) or SI units (as A 1046M). Values in inch-pound and SI units are not necessarily equivalent. Within the text, SI units are shown in brackets. Each system shall be used independently of the other.

1.6 Unless the order specifies the "M" designation (SI units), the product shall be furnished to inch-pound units.

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

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.
