Stainless Steel 420, also known as UNS S42000, is a high-carbon steel with a minimum chromium content of 12%. It is characterized by its excellent corrosion resistance, high strength, and hardenability. This martensitic stainless steel grade is often used in applications where high strength and moderate corrosion resistance are required, making it a versatile choice for various industries. The 420 stainless steel is particularly noted for its ability to be hardened through heat treatment, enhancing its mechanical properties. This makes it ideal for manufacturing blades, surgical instruments, cutlery, and various other tools that require a sharp edge and high wear resistance. Additionally, it is used in the production of valves, gears, shafts, and other components that must endure high stress and impact. Read More
