35CrMo steel is mainly used to manufacture important parts in various machines that bear impact, bending and torsion, and high loads, such as rolling mill herringbone gears, crankshafts, hammer rods, connecting rods, fasteners, steam turbine engine main shafts, axles, and engines Transmission parts, large motor shafts. It can also replace 40CrNi to manufacture high-load transmission shafts, steam turbine engine rotors, large-section gears, supporting shafts (diameter less than 500MM), etc.; process equipment materials, pipes, welding materials, etc. 35CrMo steel can also be used as important structural parts that work under high loads, such as transmission parts of vehicles and engines; rotors, main shafts, heavy-duty transmission shafts of steam turbine generators, and large-section parts.
