Stainless Steel 420 Hollow Bar is a high-carbon martensitic stainless steel that contains around 12-14% chromium and up to 0.15% carbon. This unique composition offers decent corrosion resistance in mild environments and remarkable hardness after heat treatment. The hollow bars boast a tensile strength of about 700-850 MPa and a hardness range of 50 HRC when hardened. They exhibit good wear resistance and moderate impact strength. Notably, Stainless Steel 420 is magnetic in both its annealed and hardened states and can be polished to a brilliant finish, enhancing both its aesthetic appeal and functional properties.

SS 420 hollow bars' excellent wear resistance enhances their performance by ensuring durability in high-friction environments. This property makes them ideal for cutting tools, medical instruments, and mechanical components, reducing maintenance needs and extending service life in demanding applications.
SS 420 hollow bars offer moderate high-temperature resistance but are generally not ideal for prolonged exposure to extreme heat. Their performance is best in applications requiring hardness and corrosion resistance under controlled or moderately elevated temperature conditions.
Stainless Steel 420 Hollow Bars find their place in applications where high hardness, moderate corrosion resistance, and excellent machinability are crucial. Common uses include the manufacturing of surgical instruments, cutlery, shear blades, valves, shafts, and bushings. They are frequently utilized in the food processing sector, automotive components, pump shafts, and parts that require wear resistance, such as gears and bearings. The hollow design allows for weight reduction and material savings in machined components. These bars are also popular for decorative purposes, where a polished surface and reliable mechanical strength are essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
