What is equivalent to 34Crnimo6 alloy steel plate?

34CrNiMo6 is a . Used for large axles, machine components, tools and high strength fasteners. The steel can be induction hardened and it is weldable under certain conditions.

The primary equivalent for 34CrNiMo6 steel is AISI 4340, though other national standards also exist, including BS 817M40/EN24 (UK), SNCM439 (Japan), and GB3077: 34Cr2Ni2Mo (China). 34CrNiMo6 is a high-strength, high-toughness alloy steel used in industries like aerospace and automotive, with applications ranging from crankshafts to landing gear components.

EN10083-3 34CrNiMo6 alloy steel plates feature high strength, high wear resistance, 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, EN10083-3 34CrNiMo6 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.

EN10083-3 34CrNiMo6 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, EN10083-3 34CrNiMo6 alloy steel plates can be used to manufacture related mechanical parts after quenching and tempering.

EN10083-3 34CrNiMo6 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:

EN10083-3 34CrNiMo6 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.

EN10083-3 34CrNiMo6 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.

What is the difference between 34CrNiMo6 and 4340?

Key differences: Low-temperature toughness: 34CrNiMo6 has better corrosion resistance and high-temperature strength due to its higher chromium content; 4340 has better impact toughness at low temperatures (below -40℃) due to its high nickel content.
