Annealing is the process of heating steel above the transformation temperature and slowly cooling it to increase the workability of the metal. Nitrogen or hydrogen-based atmospheres are also required to achieve a bright annealed surface finish.
Brazing

Furnace brazing is commonly used when large batches of parts are to be processed at one time. We provide a reducing atmosphere to help you produce higher quality joints, with controlled heat temperatures and improved production rates.
Carburizing & Hardening

Carburizing is a heat treatment process in which steel absorbs carbon while the metal is heated. Our technology provides ideal conditions for better control and repeatability.
Gas Quenching & Inerting
