Displacing oxygen creates the potential for an oxygen deficient or hazardous atmosphere, which is an occupational hazard. The Occupational Safety and Health Administration (OSHA) specifies that a hazardous atmosphere may include one where the oxygen concentration is below 19.5% (or above 23.5%).

Inert gases, such as argon (Ar) or nitrogen (N 2), and reducing gases such as hydrogen (H 2), are used to prevent oxidation, whilst oxidising gases, such as oxygen (O 2) or nitrous oxide (N 2 O), are used to promote oxidation. The choice of atmosphere is entirely dependent on the requirements of the heat treatment process.

The Role of Inert Gases in Heat Treating. The inert gases most commonly used in heat treatment processes are argon (Ar), helium (He), and nitrogen (N2), and they are often used in the following combinations: Ar/He, Ar/He/ N2, and N2/He. Many types of non-ferrous metals are heat treated in an inert atmosphere, including copper, brass, …

What is Inert Atmosphere Processing? Inert Atmosphere Processing is the heat treatment of a component in a furnace atmosphere which will not react with the material being processed. Inert gases are argon and helium. Nitrogen is not a truly inert gas, reacting with certain materials (e.g. stainless steels) at elevated temperatures.*
