440C Stainless Steel Coil Description

440C stainless steel coil has good cutting and wear resistance for the high carbon content. Besides, it has excellent corrosion resistance and is resistant to the erosion of a variety of chemical corrosive media. 440C has excellent hardness owing to its high carbon content. Heat treatment and quenching gives it excellent cutting ability and wear resistance. In addition, 440C has a high chromium content and excellent corrosion resistance in most acidic and alkaline environments. So 440C stainless steel material is an very ideal choice for high-end manufacturing fields such as aerospace, mechanical manufacturing, electronic equipment and medical devices.
