What is martensitic stainless steel?
Standard martensitic stainless steels are: 403 stainless steel, 410 stainless steel, 414 stainless steel, 416 stainless steel, 416 (Se stainless steel), 420 stainless steel, 431 stainless steel, 440A stainless steel, 440B stainless steel and 440C stainless steel. The corrosion resistance of these steels comes from "chromium". "The chromium content ranges from 11.5 to 18%. The higher the chromium content, the higher the carbon content of the steel to ensure the formation of martensite during heat treatment. The above three types of 440 stainless steel are rarely considered to be welded. Application, and the filler metal of the 440 type component is not easy to obtain.
Martensitic stainless steel is mainly low carbon or high carbon steel with a chromium content ranging from 12% to 18%. There are three types of martensitic stainless steel grades as follows:
1. Low carbon and medium carbon 13% Cr steel.
2. High carbon 18% Cr steel.
3. Low carbon nickel (about 2%) 17% Cr steel.
Martensitic stainless steels are high-strength and corrosion-resistant and can be used to make machine parts such as steam turbine blades (1Cr13), steam-equipped shafts and tie rods (2Cr13), and parts that work in corrosive media such as valves, bolts, etc. (4Cr13). Steel grades with high carbon content (4Cr13, 9Cr18) are suitable for the manufacture of medical devices, table knives, measuring tools, springs, etc.
