Nitrogen
A multipurpose gas for the metals and materials processing industry
Nitrogen is used across numerous applications to help improve quality as well as increase efficiency and yield in metals and materials processing. Its inert nature allows it to be used to protect most molten and heated metals during processing.
We offer compressed nitrogen gas and liquid argon in a variety of purities and concentrations.
Our experienced applications teams across the globe can use their industry and application knowledge to provide you with a compressed or liquid nitrogen supply and technology solution to meet your unique needs.
Nitrogen for Metals and Materials Processing
Nitrogen can be used in a wide range of applications across metals and materials component manufacturing:
- Inerting atmosphere
- Powder atomization
- Gouging
- Thermal and plasma spraying
- Heat treating
- Brazing
- Annealing
- Carburizing/Nitriding
- Neutral Hardening
- Quenching
- Sintering
- 3D printing
- Shielding gas
- Cooling
- Cryo-treating
to provide numerous benefits, such as:
- Reducing or eliminating surface oxidation
- Improving product quality
- Increasing efficiency and yields
- Decreasing scrap

“What nitrogen purity do I need for my heat treatment process?”
That depends on your process. Nitrogen based atmospheres for metals processing have been successfully proven over many years, and due to the enormous range of requirements in furnaces for various materials and surface needs, the use of gas mixtures is now an industry standard. Different products can tolerate differing concentrations of oxidizing components in the furnace atmosphere due to additional reducing or reactive components in the blend. For this reason, the use of on-site generated nitrogen with residual amounts of oxygen can be tolerated. By understanding your oxygen tolerance levels we can help you reduce your costs. For most materials, although free oxygen is not tolerable, some oxidizing impurities may be permitted. In these cases, the on-site production of high purity nitrogen for the heat treatment of very sensitive materials may be commercially viable.
