George Metals, which specialises in premium stainless steel products, supplies important industries like tool manufacturing, engineering, automotive, and medicine. Superior mechanical qualities and exact dimensional tolerances are guaranteed by their production of stainless steel 420 bars and rods, which strictly adheres to international standards and quality specifications. These bars, which are well-known for their exceptional polishability and moderate resistance to corrosion, come in a range of sizes and finishes to accommodate a variety of industrial applications while maintaining dependable performance and affordable prices.
Stainless Steel 420 Bars/Rods are martensitic stainless steel with trace amounts of silicon, manganese, phosphorus, sulphur, and 0.15–0.40% carbon and 12–14% chromium. Because of its composition, the alloy can undergo heat treatment to increase its hardness, reaching Rockwell hardness of up to 50 HRC and tensile strength of up to 700–800 MPa. 420 has outstanding polishability and moderate corrosion resistance in mild conditions. Its mechanical and chemical properties, particularly after hardening and tempering, make it appropriate for uses requiring a high level of surface finish and moderate strength.

A wide range of applications requiring high hardness, polishability, and moderate corrosion resistance use stainless steel 420 bars and rods. Cutlery, dental and surgical tools, pump shafts, valve parts, scissors, and machine parts are among the frequently used items. For parts that need a long-lasting and easily sharpened edge, the manufacturing, automotive, and medical sectors favour 420. It is appropriate for precision components that are subjected to wear and abrasion because it can be hardened through heat treatment. 420’s bright finish and resistance to atmospheric conditions make it a reliable material for long-term use in decorative or utility applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
