AMFIN SERVICES
Industrial Metal Heat Treatment Services
Amfin provide heat treatment services to improve the mechanical properties and increase the lifespan of the metal.
Industrial batch ovens
Amfin have eight aerospace approved, industrial batch ovens that are ideal for high-temperature applications. Our Process ovens can be used in air atmospheres or inert atmospheres for oxidation-sensitive materials.
Our ovens are capable of handling Stress relief and de-embrittlement and drying operations complying to specification AMS2750, reaching a maximum temperature of 300°C.
The ovens are fitted with programmable control systems, allowing for accurate process control and improved traceability.

The different types of heat treatment
High Temperature Stress relieving
Our heat treatment process overs can be used to carry out stress relieving on metal to reduce residual stresses in the material.
The process involves heating the metal to a high temperature and then cooling it rapidly. This rapid cooling process creates a hardening effect on the metal. The heat treatment system can be used on a variety of metals, including aluminium, brass, and steel.
The process is used to improve the strength and hardness of a metal to prevent cracking or warping during subsequent machining. Additionally, high temperature stress relieving can help to improve the dimensional stability of a material.
Polyimide Curing
Polyimide curing is used to improve the dimensional stability and mechanical properties of plastics. It can also be used to improve the electrical and thermal properties of plastics.
Polyimide curing is a process in which a polyimide resin is heated in the presence of an acid or base catalyst. The heat causes the polymer chains to break down and reform which results in a harder and more durable material. The addition of the catalyst helps to speed up the process and improve the final properties of the material.
Thermal Annealing
Annealing is a heat treatment process used to modify the physical and/or chemical properties of a material. The process involves heating the material to a high temperature and then slowly allowing it to cool over several days.
Paint curing and Adhesive Bonding
Paint curing is a process where a paint film is allowed to dry and harden before being subjected to further processing.
This can improve the physical and chemical properties of the paint film, as well as the appearance.

Metal Heat treatment FAQ
Advantages of metal heat treatment
There are many advantages as to why you should use heat treatment:
- To improve the mechanical properties of a material
- To change the microstructure of a material
- To relieve stresses in a material
- To harden or soften a material
- To improve the wear resistance of a material
- To improve the corrosion resistance of a material
What metals can be heat treated?
Ferrous metals such as Iron and Steel are the biggest types of metals that are heat treated.
Hydrogen Embrittlement Relief
Embrittlement Relief is sometimes referred to as stress relief baking.
It is a heat treatment process that is used to relieve the residual stresses that are found in metals after the manufacturing process has been completed.
De-embrittlement baking is used to remove the hydrogen that is found in the metal and to improve the ductility of the metal.
This process is often used on metals that are going to be used in high stress environments, such as aircraft parts.
