Batch annealing

Stainless steels, carbon steels and non-ferrous materials are annealed to trigger the relaxation of internal stresses and give a softer product. Our ALNAT atmosphere solutions for annealing are mainly based on mixtures of nitrogen, hydrogen and hydrocarbon or nitrogen and cracked methanol. Benefits include safety, reliability, low-maintenance operation and low capital costs.



Our ALNAT solutions include bulk gas supply, related gas handling equipment, and a range of services related to the generation, use and control of atmospheres in industrial heat processing furnaces.
