420
420 is a hardenable, martensitic stainless steel similar in chemical composition to that of 410, differing primarily in carbon content. 420 stainless steel is leaner in carbon than that of 410 allowing for it to be capable of achieving a higher strength and hardness at the result of lower ductility. 420 offers comparable corrosion resistance to that of 410 and is commonly utilized for applications requiring high strength, high wear resistance, or good edge retention.
