HEAT TREATMENT

triangle

Heat treatments are processes that aim to improve the characteristics of materials, namely steel.


In partnership, DIMLASER®, provides the most diverse types of treatments for parts manufactured by Additive Manufacturing or by CNC.


Tempering

Tempering increases the resilience of iron-based alloys like steel. Can be used to change the hardness, ductility, and strength of metal, which usually makes it easier to machine.

CEMENTING

Cementing consists of adding carbonisation to the surface layer of the piece. The longer the treatment time, the larger the carbon layer. This process makes it possible to produce a piece with high surface hardness and a tenacious core.

Hardening

Hardening is used to increase the hardness of a metal. A harder metal will have a higher resistance to plastic deformation than a less hard metal.

NITRIDING

Nitring process diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on high-carbon, low-alloy steels. They are also used on medium and high-carbon steels, titanium, aluminium and molybdenum.

Stress relief

Stress relief is used to reduce the internal material stresses within a part or assembly as consequence of manufacturing processes. The resultant end item will then be less prone to dimensional variation by post manufacturing.

CARBONITRIdiNG

Carbonitriding is a surface case hardening process that produces a thin, high hardness case and is a modified form of gas carburizing. This process is typically selected for case hardening plain carbon and low alloy steels that have poor hardenability and would not normally fully transform to martensite during quenching.

Annealing

Annealing is used in aluminum, copper, steel, silver, or brass. This process increases the metal’s ductility and decreases hardness to make the metal more workable.

NITROCARBONIsATION

Nitrocarbonisation is a variant of the nitriding process, combining nitrogen and carbon to form a surface layer. This process is carried out mainly to achieve the wear resistance of the surface layer and improve the resistance to fatigue.

Precipitation Hardening

Precipitation hardening is a heat treatment process applied to various alloys to significantly increase their yield strength.
