With a typical composition of 12–14% chromium and up to 0.15% carbon, stainless steel 420 is a martensitic stainless steel that can be heat-treated for greater hardness. It has a high tensile strength (roughly 700–950 MPa) and yield strength of about 345 MPa, and it exhibits good corrosion resistance in mild environments. It has moderate ductility and excellent hardness when hardened (up to 50 HRC). When hardened, SS 420 exhibits fair machining characteristics and is magnetic both in its annealed and hardened states.

Because of its exceptional hardness and polishability, stainless steel 420 square bars and rods are frequently used in the cutlery industry to make knife blades, surgical tools, and scissors. They are also used for shafts, gears, and valve parts in the automotive industry. SS 420 is perfect for moulds, dies, and bearing assemblies in the engineering and tooling sectors. It is appropriate for pump shafts, fasteners, and springs due to its high wear tolerance and resistance to corrosion. Applications needing strength, edge retention, and abrasion resistance in dry and mildly corrosive environments favour this alloy.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
