ER630 contains about 17% Chromium, 4% Nickel, 4% Copper, and 0.3% Niobium, with low carbon content. It is a precipitation-hardening stainless steel that achieves high strength after heat treatment. Mechanical properties include tensile strength up to 150,000 psi (1030 MPa) after aging, and yield strength over 130,000 psi (900 MPa), with elongation around 15%. This mix of high hardness, strength, and moderate corrosion resistance makes ER630 ideal for welding parts that require post-weld heat treatment to regain full strength.
