Grade 420 stainless steel is a martensitic stainless steel with similar corrosion properties to type 410. Grade 420 has a higher carbon content allowing for heat treating to higher hardness values and better abrasion resistance, but with a lower impact strength. Type 420F has a higher sulfur content resulting in slightly lower enlongation.
