ASME SA588 Grade K covers 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
ASME SA588 Grade K steel in most environments is substantially better than that of carbon structural steel with or without copper addition. When properly exposed to the atmosphere,
ASME SA588 Grade K steel is suitable for many applications in the bare (unpainted) condition.
