ASTM A588/A588M A588 Grade A weathering steel plate is most common used in weathering steel industries all over the world,for high bridges built,shipping containers and other steel constructions in bad situiations.
Weathering steel grade A588 Grade A,weathering steel grade A588 Grade B,A588 Grade C and A588 Grade K.All these four weathering steel grades owned minimum 485 Mpa for tensile strength.
A588 Grade A Steel Delivery Conditions:
Hot Rolled, Cold Rolled, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP), Electroslag Remelting Technical, HIC test.
A588 Grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness.When properly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition.
