Vacuum Hardening & Tempering

In this procedure, we do deformation sensitive precision or formed components and tools which make high demands on a clean, bright surface. A modern process control guarantees optimum reproducibility. The heat treatment provisions are developed together with the customer according to the application.

Plasma Nitriding

Plasma Nitriding is a surface hardening process, in which nitrogen is diffused in to the components surface. Plasma nitriding produces high surface hardness, good wear resistance, increased fatigue strength and toughness. It is an effective way of enhancing the mechanical properties of ferrous and titanium alloy parts. Plasma nitriding is a very clean method and environment friendly process.

Induction Hardening & Tempering

Induction hardening is a type of surface hardening in which a metal part is induction-heated and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole.

Cryogenic Treatment

A cryogenic treatment is the process of treating workpieces to cryogenic temperatures (i.e. below −190 °C (−310 °F)) in order to remove residual stresses and improve wear resistance on steels and even composites. In addition to seeking enhanced stress relief and stabilization, or wear resistance, cryogenic treatment is also sought for its ability to improve corrosion resistance by precipitating micro-fine eta carbides, which can be measured before and after in a part using a quantitative metallography.

Liquid Nitridng

Liquid Nitriding is a common term for a diffusion process that is actually liquid nitrocarburizing; a thermo-chemical reaction whereby nitrogen, primarily, and some carbon are diffused into the surface of iron-based materials. The nitrogen combines with the iron to form an iron-nitride compound layer that provides improved surface properties; e.g. resistance to wear, friction, corrosion, and fatigue.

Carbonitriding

Carbonitriding is a metallurgical surface modification technique that is used to increase the surface hardness of a metal, thereby reducing wear. During the process, atoms of carbon and nitrogen diffuse interstitially into the metal, creating barriers to slip, increasing the hardness and modulus near the surface. Carbonitriding is often applied to inexpensive, easily machined low carbon steel to impart the surface properties of more expensive and difficult to work grades of steel.[1] Surface hardness of carbonitrided parts ranges from 55 to 62 HRC.

Carburising Hardening & Tempering

Carburizing is generally followed by quenching and tempering. After quenching, the outer surface becomes harder via martensitic transformation due to its higher carbon content, while the core remains relatively soft and tough. Tempering is performed to increase the toughness and ductility of the quenched part. Through carburizing and quenching plus tempering the part, the results are increased surface hardness, wear resistance, fatigue, and tensile strength, as well as the desired compressive residual stress on the surface. Consequently, the part also experiences grain growth and distortion.

Hardening & Tempering

Hardening and tempering of engineering steels is performed to provide components with mechanical properties suitable for their intended service. Steels are heated to their appropriate hardening temperature {usually between 800-900°C), held at temperature, then “quenched” (rapidly cooled), often in oil or water. This is followed by tempering (a soak at a lower temperature) which develops the final mechanical properties and relieves stresses. The actual conditions used for all three steps are determined by steel composition, component size and the properties required.
