With fast development of the automotive industry, materials used to reduce automotive weight have been developed, which, in turn, improves material properties. Automotive parts manufacturers also pay great attention to it. Ferritic stainless steel can reduce a lot of material cost for the automotive industry because it doesn＇ t contain nickel （Ni）, a kind of expensive metal. Simultaneously, ferritic stainless steel also has better pitting corrosion and intergranular corrosion resistance properties than that of austenite stainless steel. Now ferritic stainless steel has found wide applications in the automotive exhaust system ferritic stainless steel, Cr17Mo, by Baosteel is introduced The development process for ultra-low carbon and nitrogen With excellent mechanical properties, formability and corrosion resistance, the newly developed steel can be used in manufacturing center tubes, tail pipes and mufflers as low temperature parts in the automotive exhaust system.
