industrial applications for manufacturing and materials processing


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 needed for a bright annealed surface finish. 

Furnace 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 

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 atmospheric gases help achieve a consistent performance for your sintering operation.

Hot Isostatic Pressing (HIP)

Proper atmosphere control is key in hot isostatic pressing. The simultaneous application of high temperature and pressure, plus Linde's argon gas, helps improve the metal's mechanical properties.

Nitriding & Nitrocarburizing

Nitriding and nitrocarburizing can help you increase surface wear resistance. This requires a safe and reliable supply of ammonia in order to achieve excellent process results.

Aluminum Die Cooling

Nitrogen-based cooling can help with temperature control in extrusion and dross cooling applications, increase your aluminum recovery rate and maximize productivity potential.

Additive Manufacturing

Process gases play a vital role in additive manufacturing and are involved in every step of the fabrication chain – from metal powder production through 3D printing.

Concrete Manufacturing

At Linde, we have the resources to provide you with the most advanced concrete block production process, while reducing your carbon footprint.
