Stainless Steel 420 is a high-carbon, martensitic stainless steel alloy that contains about 12–14% chromium, which gives it excellent corrosion resistance and impressive hardness. Its mechanical properties include a tensile strength of approximately 700–850 MPa, yield strength of 450–600 MPa, and elongation of 12–20%, depending on the heat treatment process. After quenching and tempering, it can reach remarkable hardness levels of up to 50 HRC. This alloy is magnetic, machinable, and can be polished to a fine finish, making it perfect for components that require wear resistance, precision, and a smooth surface while still offering moderate corrosion resistance in various environments.

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 that demand high wear resistance and strength. They are particularly well-suited for manufacturing cutlery, surgical instruments, valves, and bearings due to their outstanding hardness and polishability. This material is also utilized in automotive components, aerospace parts, and industrial machinery where precision and durability are essential. Furthermore, Stainless Steel 420 is ideal for decorative elements, fasteners, and shafts that require a combination of corrosion resistance and a robust, wear-resistant surface. Mourad Metals ensures that every bar and rod meets stringent quality standards, providing peace of mind to their customers.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
