ASTM A533 Grade D CL2

ASTM A533/A533M A533 Grade D CLASS 2,ASME SA533/SA533M SA533GRDCL2 steel plate are mainly used for building pressure veesels with alloy elements Mn,Mo and Ni.Comparing with boiler steel plate A533GrDcl1,boiler steel plate A533GrDcl2 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 SA533GRDCL2.

ASTM A533 Grade D Class 2 ASTM A533/A533M Mechanical

The resistance of ASTM A533 Grade D Class 2 ASTM A533/A533M to damage under load is called its mechanical properties. The mechanical properties of steel materials are the main basis for the design and material selection of parts. The mechanical properties of steel materials will be different with different loading properties (such as tension, compression, torsion, impact and cyclic loads). Common mechanical properties include strength, plasticity, hardness, impact toughness, multiple impact resistance and fatigue limit.

The mechanical properties of ASTM A533 Grade D Class 2 ASTM A533/A533M is in line with ASTM A533/A533M. The main properties as below:
