From the brochure  'Heat treatment with a difference'.
In annealing nitrogen or hydrogen based atmospheres are required to achieve bright surface finish. We have developed technologies to optimize atmosphere costs, ensure atmosphere uniformity and thus maximize part quality.
Teaser Furnace Brazing 135x90
Furnace brazing requires atmospheres to facilitate excellent braze joints and better surface quality in mass production. Our technologies enable companies to control and optimize furnace conditions to achieve higher productivity and increased surface quality. In addition, optimized atmosphere compositions reduce total costs.
Heat treated gears, Close up.
In thermo-chemical processes such as carburizing, 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.
Teaser Neutral hardenig 135x90
Neutral hardening is the most common method to harden metals through heating and quenching. We offer gases and technologies to avoid oxidation and decarburization in the most cost-effective way possible.
Teaser Nitriding & nitrocarburising 135x90
Nitriding and nitrocarburizing 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.
Teaser Powder metal sintering 135x90
Powder metal sintering requires specific gas atmospheres in order to assist de-lubrication and to avoid decarburization. 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.
Teaser Sub-zero treatment 135x90
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.
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.
