HEAT TREATMENT COVENTRY LTD
Tool Steel Heat Treatment and Hardening
Tool steels require grade-specific heat treatment to develop hardness, wear resistance and service performance.
01
What the Process Is
Tool steel hardening uses carefully selected preheating, austenitising, cooling and tempering stages. The route varies substantially between cold-work, hot-work, high-speed and mould steel grades.
02
How the Treatment Works
The identified grade is treated to an agreed specification, with attention to section size, geometry, prior machining and the required hardness. Multiple tempering stages may be specified for particular grades.
03
Why Engineers Specify It
Correct heat treatment helps develop the properties intended by the tool-steel manufacturer while managing brittleness, retained stress and dimensional risk.
04
Typical Components and Applications
- Punches and dies
- Cutting and forming tools
- Mould components
- Jigs, fixtures, gauges and wear inserts
05
Materials, Specification and Process Control
Never describe material only as “tool steel”. Supply the full grade, manufacturer if relevant, required hardness, finished dimensions and any special treatment instruction.
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
No. Tool-steel families and individual grades require different treatment temperatures, cooling routes and tempering conditions.
That depends on grade, geometry and finishing route. Discuss critical dimensions and final grinding requirements before treatment.
Reliable treatment requires positive material identification. An assumed grade can lead to an unsuitable cycle and poor results.
