What is 39NiCrMo3 Quenching and Tempering Steel Plate

EN 10083-3 39NiCrMo3 is an alloyed heat-treatable steel characterized by its high strength, good toughness, and high hardenability, particularly in larger sections. It contains nickel and chromium for strengthening and is used in the quenched and tempered condition for dynamically stressed mechanical components like shafts, gears, and engine parts.

39NiCrMo3 is also known as AISI 9840 / 1.6510. AISI 9840 is defined as Cr-Ni-Mo series alloy steel as per USA standard ASTM A519. AISI 9840 steel is very similar to AISI 4340 steel, only the Ni element is lower, and the difference in other elements is almost negligible.

Mechanical manufacturing field

39NiCrMo3 alloy steel plates feature high strength, high wear resistance, and high harden ability, and are widely used for bearings and gears of rotating machinery, as well as valve bodies, pumps and accessories, wheels, bolts, studs, etc.

In addition, 39NiCrMo3 alloy structural steel, with its characteristics of high strength, high toughness, good harden ability and wear resistance, is used in mechanical manufacturing to make gears, connecting rods, tools, molds and other parts.

Automotive and transportation field

39NiCrMo3 high alloy steel plates are often used in automobile manufacturing and can be made into parts such as crankshafts, axles, and gears, which need to have high strength and toughness. In terms of railway transportation, 39NiCrMo3 alloy steel plates can be used to manufacture related mechanical parts after quenching and tempering.

Aerospace and military field:

39NiCrMo3 alloy special steel plates are often used to manufacture parts of aircraft and military equipment, such as gears, shafts, and engine parts, due to their excellent wear resistance and fatigue resistance.

Construction and large - scale structure field:

39NiCrMo3 hot-rolled alloy steel plates can be used to manufacture structural parts of large - scale structures such as ships and bridges, providing necessary strength and stability for these large - scale structures.

Energy and power field

39NiCrMo3 alloy steel plates can be used to make header of super heater in power station boilers, etc., and can also be used in power generation equipment, such as key parts of coal - fired, gas - fired and nuclear power generation equipment (similar to the use of other boilers and pressure vessels).

For example, after wind turbine gearbox components adopt this steel, the trouble-free operation time is increased to 25,000 hours, and the service life of drill pipe joints of oil and gas drilling equipment is extended by about 40% under the working condition of 150 MPa pressure and frequent make-and-break operations.
