product description

440C Stainless Steel Bar Description

440C stainless steel bar has good cutting and wear resistance with its high carbon content. Besides, it has excellent corrosion resistance and is resistant to the erosion of a range of chemical corrosive media. Owing to its high carbon content, 440C has excellent hardness. Heat treatment and quenching gives it brilliant cutting ability and wear resistance. In addition, there is a high chromium content in the chemical composition of 440 C stainless steel bars, which accounts for its excellent corrosion resistance in most acidic and alkaline environments. So 440C stainless steel bars are a very ideal choice for high-end manufacturing fields such as aerospace, mechanical manufacturing, electronic equipment and medical devices.
