ASTM A529/A529M-03

Standard Specification for High-Strength Carbon-Manganese Steel of Structural Quality

SCOPE
1.1 This specification covers carbon-manganese steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of buildings and for general structural purposes.
1.2 Material under this specification is available in two grades:GradeYield Strength,ksi [MPa]Thickness50 [345]50 [345]Plates to 1 in. [25 mm] thickto 14 in. [355 mm] wideBars to 31/2 in. [90 mm] Shapes with flange or leg thickness to 11/2 in. [40 mm] inclusive55 [380]55 [380]Plates to 1 in. [25 mm] thick to 14 in. [355 mm] wideBars to 3 in. [75 mm] Shapes with flange or leg thickness to 11/2 in. [40 mm] inclusive
1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A 6/A 6M for information on weldability.
1.4 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.
