420 Stainless Steel

420 stainless steel is a martensitic grade of stainless. It is magnetic and hardenable with rust resistant properties. 420 stainless is characterised by having a high carbon, and up to 14% chromium content. This mix of analysis gives our 420 stainless sheet and sections an outstanding corrosion resistance and exceptional wear properties after heat treatment. Superior to 410 and 416 for most applications. 420 stainless steel has good ductility in the annealed condition, but is capable of achieving 55HRC after treatment. Optimal corrosion resistance is realised when 420 is surface ground and polished after hardening.

420 Stainless Steel - Applications 

Typical applications for 420 Stainless Steel include fine cutlery, knives, blades, dental and surgical instruments, cutting tools, wear plates, pump components, shafts, gear pinions, cams, injection moulds, fastners and various hand tools.
