2. Martensitic stainless steel (cutting tools stainless steel): representative grade: 420
The mechanical property of martensitic stainless steel is adjustable by heat treatment. Generally speaking, it is a type of hardenable stainless steel. It is hardened after quenching. Different tempering temperatures give different combinations of hardness and toughness. This stainless steel is widely used in such industries where the requirements of corrosion resistance is not very high, plus the cutting tools and machine elements have high requirements on strength.
