HEAT TREATMENT COVENTRY LTD
Steel Carburising Services
Carburising enriches the surface of suitable steel with carbon so that a hard case can be developed over a tougher core.
01
What the Process Is
Carburising is a thermochemical diffusion treatment for suitable low-carbon and alloy case-hardening steels. Carbon is introduced at elevated temperature and the component is subsequently hardened using a controlled cycle.
02
How the Treatment Works
Carbon diffuses into the surface while the part is held in a controlled carbon-bearing environment. Process time and temperature influence the carbon profile and case depth; quenching and tempering then develop the required properties.
03
Why Engineers Specify It
The process is selected for components requiring wear resistance and contact-fatigue performance without making the full section uniformly hard and brittle.
04
Typical Components and Applications
- Gears and splined components
- Shafts and transmission parts
- Pins, rollers and bushes
- Components subject to repeated surface contact
05
Materials, Specification and Process Control
Quote requests should state the full steel grade, case-depth definition, surface and core hardness requirements, drawing dimensions, machining allowance and areas that must remain soft.
Important: suitability depends on the exact material grade, component condition, geometry and required specification. Please provide these details for technical review before treatment.

Frequently Asked Questions
Alloy content and carbon level influence hardenability, achievable core properties and the response of the carburised case.
Heating and quenching can cause dimensional change. Geometry, material and prior processing must be considered, with finishing allowance where appropriate.
Selective protection may be possible, but requirements must be identified on the drawing and reviewed before quotation.
