35CrMo belongs to the national standard alloy structural steel, the implementation of the standard: GB/T 3077-2015
35CrMo has a high static strength, impact toughness and high fatigue limit, quenching and hardenability is higher than the 40Cr, high temperature has a high creep strength and enduring strength, the long term working temperature of up to 500 ℃; cold deformation of the plasticity of the medium, poor welding. Low temperature to -110 degrees Celsius, and has a high static strength, impact toughness and high fatigue strength, good hardenability, no tendency to overheat, quenching deformation is small, cold deformation plasticity is still available, cutting and machining medium, but there is a first class tempering brittleness, weldability is not good, welding needs to be preheated before welding to 150 ~ 400 degrees Celsius, post-welding heat treatment to eliminate stress, generally used in the quenched and quenched treatment, but also in the high and medium frequency Surface quenching or quenching and low and medium temperature tempering after use. The steel is mainly used in the manufacture of a variety of machines to withstand impact, bending and twisting, high loads in the important parts.
The chemical composition of 35CrMo is as follows:
