ASTM A242 steel work/steel structure/steel machining parts is a high-strength low-alloy structural steel for welded,riveted,or bolted construction intended primarily for use as structural members where savings in weight or added durability.The atmoSPHEric corrosion resistance of the steel in most environments is substantially better than that of carbon structural steels with or without copper addition.
Thickness range is between 1.5-80mm
Width range is between 1500-3800mm
Length range is between 1000mm-12000mm
