ASTM A612 steel plate is a high-strength low-alloy (HSLA) steel plate designed for welded pressure vessels. The chemical composition of SA612 steel includes high levels of nickel, manganese, and silicon, along with trace amounts of carbon and other elements. Specifically, this steel plate contains 8-9% nickel, 0.50-1.50% manganese, and 0.40-1.00% silicon. The carbon content is kept at a minimum to ensure good weldability and reduce the risk of brittleness.

ASTM A612 Mechanical Properties

SA612 steel has a minimum tensile strength of 690 MPa and a minimum yield strength of 415 MPa. The elongation and fracture toughness of this steel are also impressive, making it an excellent material for high-stress applications. Additionally, SA612 steel exhibits good corrosion resistance due to the high levels of nickel and manganese.
