The difference between HG70 steel plate and 45 # steel: 45 steel belongs to GB699 "(****) carbon structural steel" and 40Cr belongs to GB3077 "alloy structural steel". The difference is after the heat treatment. The main role of Cr in heat treatment is to improve the hardenability of steel. Due to the improved hardenability, the mechanical properties such as strength, hardness and impact toughness of 40Cr after quenching (or quenching and tempering) treatment are also significantly higher than those of 45 steel.
