35CrMnSiA alloy steel plate has good comprehensive mechanical properties, high strength, enough toughness, hardenability and welding ability (preheat), and good processing formability after heat treatment. But the corrosion resistance and oxidation resistance of 35CrMnSiA alloy steel plate is low. Therefore, 35CrMnSiA alloy steel plates are usually used after low temperature tempering or equal temperature quenching.
