Through Hardening

Through Hardening


Hardening process that is achieved by austenising and quenching with a carbon neutral atmosphere (i.e. no carbon enrichment). This will provide a tensile strength (throughout the part) upon quenching which is tempered primarily to increase the ductility and toughness.

Component suitability

  • Axles
  • Shafts
  • Bushes
  • Pins

Advantages of Gas Carburising

  • Through hardening can provide high strength throughout the part.

Typical materials

4140, XK1340, High carbon bearing steels, tool steels

Gas Carburising Furnace types available

Sealed quenched furnaces, rotary retort furnaces.

Possible limitations

Distortion of component could be expected and a grinding allowance may be necessary.
