| Application | Structure and Industrial |
40CrNiMoA steel is a Chinese alloy steel, has high strength, toughness and good hardenability, and has anti-overheating stability, but has high white point sensitivity, temper brittleness and poor weldability. Preheating is required before welding, and stress relief treatment is required after welding.
40CrNiMoA steel is used after quenching and tempering, and is used to manufacture important parts requiring good plasticity, high strength and large size. For example, heavy-duty shafts in heavy-duty machines, steam turbine shafts with diameters greater than 250 mm, blades, transmissions, fasteners, crankshafts, gears, etc., can also be used for rotor shafts and blades operating at temperatures exceeding 400 °C.
