What is Stainless Steel 422 Bars ?

Stainless Steel 422 Bars/Rods contain chromium (12–14%), molybdenum, tungsten, and controlled carbon content to enhance strength and creep resistance. This grade provides a tensile strength of about 700–900 MPa and yield strength of around 500 MPa. With approximately 18% elongation and Rockwell hardness up to 40 HRC, SS 422 maintains stability at high temperatures. It shows excellent resistance to oxidation up to 1200°F (650°C). The alloy is magnetic, heat-treatable, and weldable under controlled conditions. These combined properties make SS 422 a versatile choice for industries needing high-strength, heat-resistant stainless steel.
