Grade 420 Stainless Steel

 420 stainless steel is a martensitic alloy melted as AOD or AOD + ESR.  It has higher carbon than the 410 and 416 alloys giving it a higher hardness.    This grade has excellent corrosion properties when hardened and offers good ductility in the annealed condition.  This grade is widely used as cutlery as well as molds and dies.
