ASTM A285 ASTM A283 Steel Plate

Short Description:

ASTM A285 is a type of ordinary carbon steel intended for fusion-welded pressure vessel equipments as boiler, storage tank, heat exchangers, etc. With 3 steel grades (Grade A, Grade B, Grade C) covering tensile strength range from 310-515Mpa,usually ASTM A285 steel plate is delivered as-rolled condition. made by killed, semi-killed, capped or rimmed steel practices according to the end users’ requirement.

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.
