Case Hardening Steel (Grade 20MNCR5)

Grade Introduction:

20MnCr5 steel is a low alloyed engineering case hardening steel for parts that require core tensile strength of 1000 – 1300 N/mm² and good wearing resistance.

This steel is carburizing steel used for components requiring high wear resistance surface, coupled with tough cores to resist shock loads and strength to give large service life.

Supplied Condition:

As Rolled

Grade Applications:

20MnCr5|1.7147 gearing steel is widely used for a variety of applications in the used to the gearings in rotating machinery. Typical applications such as valve bodies, pumps, and fittings, the high load of the wheel, bolts, double-headed bolts, gears, internal combustion engine. Electric locomotives, machine tools, tractors, steel rolling equipment, boring machine, railway vehicle, and mining machinery transmission shaft on the steel ball, roller and shaft sleeve, etc.
