Ferric stainless steel which mainly exists in ferric tissue in the use state. Chromium content is at 11%~30%, with a somatic cubic crystal structure. This kind of stainless steel generally does not contain nickel, sometimes also contains a small amount of Mo, Ti, Nb and other elements, this kind of steel has large thermal conductivity, small expansion coefficient, good oxidation resistance, good stress corrosion resistance and other characteristics, mostly used in the manufacture of atmosphere, water vapor, water and oxidative acid corrosion resistant parts.
