Protective Gas Heat Treatment  Manufacturers, Traders, Suppliers

procedure: Case hardening, neutral hardening, tempering, ageing, annealing, e.g. stress relief annealing, gas nitriding, carbonitriding, nitrocarburizing Protective gas heat treatment covers the field of thermal and thermochemical processes. In addition to hardening and tempering under inert gas with subsequent oil quenching, thermochemical processes can specifically modify the surface properties of components by enriching the surface layer with carbon and/or nitrogen. The processes are carried out by state-of-the-art process-supported program controls, whereby the set program parameters are continuously analyzed and updated. The available plant is fully automated and therefore has an automatic loading/unloading of the aggregates. The automation ensures a high quality standard of the products as well as particularly favourable delivery dates. Precision hardening Deutsche Edelstahlwerke Härterei Technik GmbH in Lüdenscheid has developed a process that reduces distortion to a minimum when hardening strips. The advantages are reduced grinding mass and therefore the savings are interesting for the final grinding. Application examples:
