Product Introduction
ASTM A283 is designed as a type of carbon steel plate for general structural purpose, this steel has low and intermediate tensile strength, it has 2 steel grades(Grade C, Grade D) . For steel plate made from coils or with no heat treatment, additional test is required for its stress relieving, usually after steel coil is decoiled, inspection, conditining, heat treatment are required before delivering. ASTM A283 is only used for structural purpose, while ASME SA283/SA283M steel plate could also be used in boiler and pressure vessel manufacture.ASTM A285 STEEL PLATE Chemical Composition
