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.
