420 Stainless Steel Strip
What is 420 Stainless Steel Strip?
420 stainless steel is a martensitic stainless steel containing 12% chromium, which imparts good corrosion resistance. In its annealed state, it exhibits good ductility and can be hardened up to 500HB, the highest achievable for this chromium grade. Martensitic stainless steels are renowned for their high hardness; however, they typically have poor weldability and require final hardening and tempering. This steel is magnetic, and welding is generally not recommended.
Features of 420 Stainless Steel Strip
420 stainless steel offers excellent strength, increased hardness, and superior wear resistance due to its high carbon content. While these features make it exceptionally strong, they also result in low ductility and challenging weldability. Its corrosion resistance is moderate, making it ideal for applications where mechanical strength is prioritized over resistance to corrosive environments.
The physical properties of 420 stainless steel can be significantly altered by any heat treatments it undergoes, allowing for customization to meet specific application requirements. For precise physical properties tailored to your needs, consulting with our materials specialist is recommended to ensure the suitability of 420 stainless steel for your specific application.
