Annealed (N2+H2) -Hardening (N2)

The advantages of choosing Air Liquide for your Annealing heat treatments

Meet your quality requirements

Our gas solutions include nitrogen and high purity nitrogen and hydrogen mixtures with very low humidity, CO2 or O2 contents adapted to your needs: reducing or protective atmospheres against decarburization when enriched with propane or natural gas.

Facilities to improve your performance

Depending on your needs, configuration of your workshop, type of heating and cooling cycles, material to be treated; we design and supply gas control panels suitable for one or more ovens. Thus it is possible to obtain optimum flexibility and productivity: less downtime between cycles, fewer post-treatments and better performance on simple metals (iron-carbon, etc.) or more complex alloys.

Our services to get the most out of your ovens

To enable you to produce in complete safety, Air Liquide gives you the benefit of its solid experience in the implementation of gases as well as its metallurgical skills, by offering you:

1. Control of treatment atmospheres,
2.  Maintenance of equipment and troubleshooting of your gas installations.
3.  Gas handling and safety training.
