Product Description
420 Stainless Steel Strip & Coil
Grade 420 stainless steel is a high-carbon martensitic steel with a minimum chromium content of 12%. This material can be hardened through heat treatment and offers excellent ductility in its annealed state. When polished, surface grounded, or hardened, it provides superior corrosion resistance properties. Grade 420 achieves the highest hardness (up to 50HRC) among all stainless steel grades containing 12% chromium.
