Praxair’s hydrogen and nitrogen gases are used in various forms of annealing. 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. We have developed technologies to help you obtain atmosphere uniformity and maximize your part quality.
Brazing is a joining process that heats filler metal and evenly distributes it between two parts. 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
Furnace inerting and parts quenching are common heat treating applications. We offer gases in a variety of supply systems to meet your process requirements.
The sintering process uses compressed metal or ceramic powders to form various shapes. Our atmosphere gases help achieve a consistent performance for your sintering operation.
