HEAT TREATMENT COVENTRY LTD
Annealing and Normalising Services
Annealing and normalising are controlled thermal treatments used to modify structure, hardness, machinability and the condition of suitable metals.
01
What the Process Is
Annealing is a broad group of treatments involving controlled heating and cooling to obtain a required material condition. Normalising is a steel treatment in which cooling is normally carried out in air to refine and homogenise structure.
02
How the Treatment Works
The cycle is selected from the material grade, starting condition and objective. Heating rate, soak, atmosphere and cooling route are controlled because they influence scale, decarburisation, hardness and microstructure.
03
Why Engineers Specify It
Depending on grade and specification, these treatments may improve machinability, reduce hardness, refine grain structure, homogenise prior processing or prepare material for a later operation.
04
Typical Components and Applications
- Forgings and castings
- Fabricated or formed parts
- Bars, blanks and machined components
- Material requiring preparation for machining or further heat treatment
05
Materials, Specification and Process Control
State whether full annealing, process annealing, spheroidise annealing, normalising or another defined condition is required. The material grade and desired outcome are essential.
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. They use different cycles and cooling conditions and produce different structures and properties.
Many annealing treatments reduce hardness, but the result depends on material, starting structure and the specified cycle.
“Anneal” can mean different processes. The drawing or purchase order should identify the intended treatment and acceptance requirement.
