Stainless Steel 420 Bars and Rods are made from high-carbon martensitic stainless steel, typically containing 12–14% chromium and 0.15–0.40% carbon. This unique composition enables the material to be hardened through heat treatment, achieving impressive tensile strengths of around 700–900 MPa and hardness levels up to 50 HRC. It boasts excellent wear resistance, moderate corrosion resistance, and good toughness. Additionally, 420 stainless steel is known for its machinability in the annealed state and can be polished to a sleek, shiny finish, making it ideal for applications that require both strength and an attractive appearance.

Stainless Steel 420 Bars and Rods are known for their excellent hardness, corrosion resistance, and wear resistance. They are a high-carbon steel that can be heat-treated for maximum hardness and are ideal for applications that require strength and durability, such as cutlery, surgical instruments, and valve parts.
Stainless Steel 420 has higher carbon content compared to other grades like 304 or 316, which allows it to be hardened through heat treatment. This makes it particularly suitable for applications that demand high strength, hardness, and wear resistance, although it may not offer the same corrosion resistance as other austenitic grades.
Stainless Steel 420 Bars and Rods find extensive use in applications where hardness, wear resistance, and moderate corrosion resistance are essential. They are perfect for crafting cutlery, surgical instruments, valve components, bearings, and precision parts. Moreover, 420 bars and rods are utilized in tooling, dies, and molds where durability under repeated mechanical stress is crucial. Industries such as medical, food processing, automotive, and chemical processing depend on 420 stainless steel for components that demand long-lasting performance and dimensional stability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
