ASTM A588 steel plate steel high-strength low-alloy structural steel

ASTM A588 steel plate introduction: ASTM A588 steel plate is a high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in weight or added durability are important. The atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition. When properly exposed to the atmosphere, this steel is suitable for many applications in the bare (unpainted) condition. This specification is limited to material up to 8 in. [200 mm] inclusive in thickness.

Application

ASTM A588 steel plate application:
Compared with ASTM A36 and ASTM A572-50 carbon steel, ASTM A588 steel plate have better cossrosion resistant characteristic. Use ASTM A588 steel plate instead of common carbon steel which make the structure lighter for it has higher strength. ASTM A588 steel plate has many application fields: outdoor sculptures, crane, bridges, rail cars, transmission towers, highway poles and shipbuilding.
