HEAT TREATMENT COVENTRY LTD
Steel Hardening and Tempering
Hardening and tempering develops a controlled balance of hardness, strength and toughness in suitable steels.
01
What the Process Is
Hardening transforms the steel microstructure through controlled heating and cooling. Tempering follows to reduce brittleness and adjust the final combination of hardness and mechanical performance.
02
How the Treatment Works
The component is heated according to its grade and section, quenched using a suitable medium, then tempered at a selected condition. The full cycle must reflect material, geometry, prior condition and final specification.
03
Why Engineers Specify It
The treatment is widely specified where components need greater strength, wear resistance or hardness together with sufficient toughness for service.
04
Typical Components and Applications
- Shafts, pins and couplings
- Machine components and wear parts
- Fasteners and structural engineering parts
- Tools and fixtures made from suitable grades
05
Materials, Specification and Process Control
Provide the steel designation, starting condition, required hardness or mechanical property, critical dimensions and any test or certification requirement. Distortion risk must be considered for complex or slender parts.
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
As-hardened steel may be too brittle for service. Tempering adjusts hardness and toughness to the specified balance.
A stated range can be reviewed when the steel grade, section size and test method are supplied.
Some dimensional change is possible during heating and quenching. Risk depends on geometry, material, residual stress and prior processing.
