Martensitic stainless steel


Stainless steels that can adjust their mechanical properties through heat treatment are, in general, a type of hardenable stainless steel. Typical grades are Cr13 type, such as 2Cr13, 3Cr13, 4Cr13 and so on. High hardness after the fire, different tempering temperatures have different toughness combinations, mainly used for steam turbine blades, cutlery, surgical instruments. According to the difference in chemical composition, martensitic stainless steel can be divided into martensitic chromium steel and martensitic chromium nickel steel. According to different organization and strengthening mechanism, it can be divided into martensite stainless steel, martensite and semi-austenitic (or semi-martensitic) precipitation hardening stainless steel and maraging stainless steel.
