Gas Carburising
Process
Gas Carburising is a case hardening process in which carbon (introduced by carbon rich gas atmosphere) is dissolved at the surface of a steel component to produce upon quenching a hardened surface layer to a required depth.
Component suitability
- Gears
- Shafts
- Levers
Advantages of Gas Carburising
- Produces a hard wearing surface while maintaining a core strength (depending on the material)
- Parts may be selectively carburised on certain surfaces by applying a protective coating to non carburised surfaces
Typical materials
EN36A, 8620 and other designated case hardening alloyed steel.
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.
