A-588 High-Strength Low-Alloy, HSLA, Structural Steel with 50 ksi Minimum Yeild Point to 4″ Thick
This specification covers high-strength, low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction with atmospheric corrosion resistance. Heat analysis shall be performed wherein the low-alloy structural steel materials shall conform to the required chemical composition for carbon, manganese, phosphorous, sulfur, silicon, nickel, chromium, molybdenum, copper, vanadium, and columbium. Steel samples shall also undergo the tensile test and conform to required values of tensile strength, yield point, and elongation.
The A588 specification is intended primarily for use in welded bridges and other structures where savings in weight or added durability is important along with the longer life cycle due to its corrosion resistant properties.
The atmospheric corrosion resistance of A588 is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition. When properly exposed to the atmosphere, A588 is suitable for many applications in the unpainted condition.
