■ Overview
ASTM A533/A533M A533 Grade A CLASS 2,ASME SA533/SA533M SA533GRACL2 steel plate are mainly used for building pressure veesels with alloy elements Mn and Mo.Comparing with boiler steel plate A533GrAcl1,boiler steel plate A533GrAcl2 owned a higher yield strength(Min.485Mpa) and tensile strength(620-795Mpa),so pressure vessel steel plates also be named as high strength steel plates which can be bear the higher strength surroundings.Ultrasonice examination shall be done after rolled steel plates SA533GRACL2.
