But at the same time, its corrosion resistance and oxidation resistance is low. Therefore, GB/T 11251 35CrMnSiA hot rolled structure steel plates are usually used after low temperature tempering or equal temperature quenching. GB/T 11251 35CrMnSiA hot rolled structure steel plates chemical composition:
GB/T 11251 40Cr hot rolled structure steel plates - Bebon The hardenability of the steel is good. GB/T 11251 40Cr hot rolled structure steel plate is also suitable for cyanidation and high frequency quenching in addition to quenching and tempering treatment. The cutting performance is better when the hardness is from HB174 to 229, the relative machinability is 60%.
