Ferritic stainless steel in the service state. The content of chromium is 11%~30%, and has the structure of bcc. This kind of steel does not contain nickel, sometimes also contain a small amount of Mo, Ti, Nb and other elements, this kind of steel with high heat conductivity, low expansion coefficient, good oxidation resistance and anti stress excellent characteristics of stress corrosion, used formanufacturingthecorrosionresistanceofthe atmosphere, water vapor, waterandoxidizing parts. This kind of steel has some disadvantages, such as poor plasticity, low plasticity and corrosion resistance after welding, which limits its application. The application of refining technology (AOD or VOD) can greatly reduce the carbon, nitrogen and other interstitial elements, thus making this kind of steel widely used
