Product Description

20CrNiMo steel is originally the steel number 8620 in AISI and SAE standards.The hardenability is similar to that of 20CrNi steel.Although the Ni content in the steel is half of that of 20CrNi steel, the upper part of the austenitic isothermal transition curve shifts to the right due to the addition of a small amount of Mo element.Due to the proper increase in Mn content, the hardenability of this steel is still very good, and the strength is higher than that of 20CrNi steel.Often used in the manufacture of small and medium-sized cars, tractor engines and gear transmission system;It can also replace 12CrNi3 steel to manufacture carburized parts and cyanidation parts with high core performance, such as the jaw and the cone body of the cone bit for oil drilling and metallurgical opencast mining.20CrNiMo has good comprehensive properties of molybdenum and can also withstand certain temperature.Forgings of connecting rod valve sections for geared whole rotor internal combustion engines for the manufacture of steam turbines.
