Stainless Steel 420 Square Bars and Rods are a martensitic stainless steel grade celebrated for their high hardness, strength, and moderate resistance to corrosion. Typically, their composition features 12–14% chromium, up to 0.15% carbon, along with trace amounts of manganese, silicon, and nickel. These bars and rods boast excellent machinability and can be hardened through heat treatment. In terms of mechanical properties, they showcase a tensile strength of 700–850 MPa, a yield strength of around 450–500 MPa, and hardness levels ranging from 200 to 300 HB, making them ideal for precision components that demand wear resistance and durability.
