35CrMo alloy structural steel has high static strength, impact toughness and higher fatigue limit, higher hardenability than 40Cr, high creep strength and lasting strength at high temperatures, long-term working temperature up to 500℃; Medium plasticity and poor weldability during cold deformation. Low temperature to -110 degrees Celsius, and has high static strength, impact toughness and high fatigue strength, good hardenability, no tendency to overheat, small quenching deformation, plasticity when cold deformation, medium machining, but there is a class of temper brittleness, weldability is not good, pre-welding to preheat to 150~400 degrees Celsius, post-welding heat treatment to eliminate stress, Generally used after tempering treatment, it can also be used after high and medium frequency surface quenching or quenching and low and medium temperature tempering. Delivery status: Normalizing or normalizing + tempering, tempering.

35CrMo alloy steel manufacturing purposes

For the manufacture of important parts in various machines that withstand impact, bending and twisting and high loads, such as rolling mill herringbone gear, crankshaft, hammer rod, connecting rod, fastener, turbine engine spindle, axle, engine transmission parts, large motor shaft, perforator in petroleum machinery, boiler bolts with operating temperature below 400 degrees Celsius, nuts below 510 degrees Celsius, High pressure seamless thick wall pipe in chemical machinery (temperature 450~500 degrees Celsius, non-corrosive media); It can also replace 40CrNi for manufacturing high-load drive shaft, turbine engine rotor, large-section gear, supporting shaft (diameter less than 500MM), etc. Process equipment materials, pipes, welding materials, etc. It can also be used to manufacture standard parts such as groove pins.
