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.

ATMOSPHERIC HEAT TREATMENT

Controlled Processing for Manufactured Components

This service sits within HTC’s atmospheric heat-treatment offering for manufacturers and engineering supply chains. The furnace environment and thermal cycle are controlled for repeatable results appropriate to the component and specification. Exact atmosphere, capacity and process parameters are confirmed only after technical review.

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.

Typical Components and Applications

  • Gears and splined components
  • Shafts and transmission parts
  • Pins, rollers and bushes
  • Components subject to repeated surface contact

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.
