Hrc Mild Ms Iron Black Cold Price Sa A516 Gr 70 Low Carbon Steel Sheet Coil Plate
Steel Plate: ASTM A516 Grade 70
ASTM A516 Gr 70 Rolled Plate is a manganese, phosphorus, sulfur, and silicon alloy with a mild carbon content. These additional alloying elements boost strength and adaptability in high-stress applications such as pressure vessels needing moderate to low temperatures and notch toughness.
There are further tests available, such as charpy impacts, ultrasonic examination, and carbon equivalency. All plates thicker than 1-1/2" must be normalized. See ASTM A516-70 Normalized for further details.
