Stainless steel is divided into martensite and austenite, ferrite and duplex. 1. Martensitic chromium stainless steel is mainly low-carbon or high-carbon steel with chromium content in the range of 11.5%-18%. Designations 403, 410, 414, 416, 416 (Se), 420, 431, 440A, 440B and 440C, the corrosion resistance of these steels comes from “chromium”. The martensitic stainless…
