Stainless Steel 420 is a martensitic stainless steel celebrated for its impressive hardness, outstanding wear resistance, and polishability. Chuck Metals provides 420 bars and rods that boast a superior surface finish and precise dimensions, making them perfect for demanding applications. These bars excel in environments where strength, durability, and moderate corrosion resistance are essential, along with easy machinability.
Stainless Steel 420 (UNS S42000) is a high-carbon martensitic stainless steel that contains 12–14% Chromium and 0.15–0.40% Carbon, along with trace amounts of Manganese, Silicon, and Sulfur. When heat-treated, 420 can reach a hardness of up to 50 HRC. It provides a tensile strength ranging from 655 to 860 MPa and demonstrates good wear and fatigue resistance. This alloy is magnetic in all conditions and offers moderate corrosion resistance in water, steam, mild acids, and food environments. 420 bars and rods are perfect for heat treatment, delivering both strength and machinability for mechanical and structural applications.
