Systems for controlled-atmosphere hardening, semi-vacuum hardening, carburisingSystems for controlled-atmosphere hardening, semi-vacuum hardening, carburising Components specially designed for use in standard hardening furnaces enable hardeningprocesses under inert gas, semi-vacuum hardening, carburising, etc. These controlled-atmosphere systems are modular in design and can be enlarged to form compact hardening systems. For many of these special heat treatment processes, such hardening systems are a very cost-efficient solution for the user. We can conduct tests and experiments for you in our Test Centre. Hardening Box System –Hardening, carburising, nitriding up to 1100 °CAll hardening boxes match the inside dimensions of the annealing furnacesThe addition of carburising granulate, neutral annealing carbon, nitriding and borating powder ensures the respective surface changes in workpieces.Also available with gas connection for almost oxidation-free inert-gas hardening of heavy partsEasy handling, reliable processing
