Product Description

40Cr belongs to gb3077 “alloy structural steel”. The difference is after heat treatment. The main function of Cr in heat treatment is to improve the hardenability of steel. Due to the improvement of 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. However, due to the strong hardenability, the internal stress of 40Cr during quenching is greater than that of 45 steel. Under the same conditions, the cracking inclination of 40Cr material is greater than that of 45 steel. Therefore, in order to avoid workpiece cracking, 40Cr quenching mostly uses oil with low thermal conductivity as the quenching medium (sometimes double liquid quenching method is also used, as the saying goes, water quenching oil cooling), while 45 steel uses water with high thermal conductivity as the quenching medium.
