15-5 Stainless Steel

15-5Stainless Steel 15-5 is a precipitation hardening martensitic stainless steel. It is used in applications requiring better corrosion resistance and transverse properties compared to other similar martensitic grades. Strength and toughness desired can be altered by temperate range in the heat treatment process.
