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 industries where high hardness, wear resistance, and moderate corrosion resistance are crucial. Typical applications include surgical instruments, cutlery, valve components, pump shafts, and molds. These bars are also utilized in the automotive, aerospace, and engineering fields for parts that experience significant mechanical stress. Thanks to its ability to achieve high hardness through heat treatment, SS 420 is an excellent choice for blades, tools, and precision-machined components. It performs optimally in mildly corrosive environments, making it a go-to material for applications where strength and durability take precedence over high corrosion resistance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
