Produced under rigorous quality control standards with precise dimensional accuracy, their SS 420 Rectangular Bars cater to diverse industries, including tooling, automotive, surgical equipment, and general engineering throughout the United States and beyond.
Stainless Steel 420 is a martensitic stainless steel that contains about 0.15–0.40% carbon and 12–14% chromium, along with small amounts of manganese, silicon, and nickel. It boasts impressive hardness (up to 50 HRC after heat treatment), good tensile strength ranging from 700–1000 MPa, and moderate corrosion resistance in mild environments. Its machinability improves when annealed, while its mechanical strength enhances with hardening and tempering. SS 420 is magnetic in all conditions and offers high polishability, making it an excellent choice for both aesthetic and functional industrial components.

Stainless Steel 420 Rectangular Bars find extensive use in tool and die manufacturing, automotive parts, surgical instruments, cutlery, and mechanical components. Thanks to their superior surface finish and hardness, they are ideal for mould bases, shafts, shear blades, valve parts, and hand tools. In the medical sector, SS 420 is favored for instruments that require sterilization and repeated use. Its corrosion resistance and ability to retain sharp edges make it perfect for cutting applications. Moreover, industries that deal with light to moderate corrosive environments highly value these bars for their reliability and performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
