Heat Treating for Aerospace & Aircraft 

linde Heat Treating, Atmospheres, and Metal processing for the Aerospace industry

The right atmosphere to strengthen your aircraft

When it comes to metal treating processes for your aircraft components, Linde can help your business take off. Heat treating enhances the strength and durability of metals. We offer a diverse portfolio of industrial gases for various heat treating applications and will work with you to make highly reproducible parts, take control of your process and build some of the toughest aircraft possible. We'll help you find ways to treat your metals more efficiently, so you never have to choose between cost and quality.



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

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 Furnace

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.
