ASTM A529/A529M-05

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

ABSTRACT
This specification covers high-strength 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. Materials considered here are available in Grades 50 [345] and 55 [380]. Steel specimens shall be killed, and as such, be affirmed in the corresponding test report. Heat and product analysis shall be performed wherein steel materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, copper, columbium, chromium, nickel, molybdenum, and vanadium. Steel specimens shall also undergo tensile tests and shall conform to required values of tensile strength, yield strength, and elongation.
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:Grade Yield Strength,ksi [MPa] Thickness 50 [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.
