Through Hardening
Process
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.
