Heat Treatment

Heat treatment involves controlling numerous parameters in order to achieve specific metallurgical properties in a given material. We offer technologies and in-depth know-how to enable precision control of some of the most critical parameters within the various heat treatment processes. In addition, we provide the full range of gases to form furnace atmospheres.

Annealing

In annealing nitrogen or hydrogen based atmospheres are required to achieve bright surface finish. We have developed technologies to optimise atmosphere costs, ensure atmosphere uniformity and thus maximise part quality.

Furnace Brazing

Furnace brazing requires atmospheres to facilitate excellent braze joints and better surface quality in mass production. Our technologies enable companies to control and optimise furnace conditions to achieve higher productivity and increased surface quality. In addition, optimised atmosphere compositions reduce total costs.

Carburising & Carbonitriding

In thermo-chemical processes such as carburising, precise carbon potential control is essential to achieve the desired product specifications. Our systems provide leading atmosphere supply and control functionality for furnaces to address these demanding conditions.

Neutral Hardening

Neutral hardening is the most common method to harden metals through heating and quenching. We offer gases and technologies to avoid oxidation and decarburisation in the most cost-effective way possible.

Nitriding & Nitrocarburizing

Nitriding and nitrocarburising can help you increase surface wear resistance. This requires a safe and reliable supply of ammonia in order to achieve excellent process results. In addition to supplying the required gases, we also provide you with leading process know-how.

Powder Metal Sintering

Powder metal sintering requires specific gas atmospheres in order to assist de-lubrication and to avoid decarburisation. In addition to supplying the required gases such as nitrogen, hydrogen and carbon monoxide, we offer leading technologies to control the carbon potential and the uniformity of the sintered parts.

Sub-Zero Treatment

Sub-zero treatments using liquid nitrogen help to improve mechanical properties such as hardness and wear resistance. In addition to liquid nitrogen, we also offer cryogenic cooling equipment in various standard and tailored sizes to improve efficiency, lower heat loss and reduce gas consumption.

Gas supply

We supply the full spectrum of industrial and speciality gases required for any heat treatment process through either cylinder and bulk delivery or through our Ecovar onsite supply solutions ensuring highest safety standards.

Service

Various industrial gases might be stored in different forms and at different locations in your plant. With our Accura and Seccura solutions you will have fully automated tracking and monitoring possibilities and you will ensure never to run out of gas and to risk production stops.
