35CrMo steel is the specification number of alloy structural steel (alloy quenched and tempered steel), which is mainly used to manufacture important parts in various machines that are subjected to impact, bending torsion and high load.

35CrMo alloy structural steel has high static strength, impact toughness and high fatigue limit, higher hardenability than 40Cr, high creep strength and lasting strength at high temperature, long-term working temperature up to 500℃; cold When 35CrMo steel deformed, the plasticity is medium, and the weldability is poor.

Low temperature to -110 degrees Celsius, and 35CrMo steel has high static strength, impact toughness and high fatigue strength, good hardenability, no overheating tendency, small quenching deformation, acceptable plasticity during cold deformation, medium machinability, but some The first type of temper brittleness, poor weldability, need to be preheated to 150~400 degrees Celsius before welding, and post-weld heat treatment to eliminate stress.

35CrMo steel is generally used after quenching and tempering treatment, and it can also be used after surface quenching or quenching at high and medium frequency and tempering at low and medium temperature. Production implementation standard: GB/T11251-2009. Delivery status: normalized or normalized + tempered, quenched and tempered.
