Frequently, nitrogen is used to purge heat treat furnaces and reflow solder baths, preventing oxidation of the metal surface and minimizing dross generation. In addition, furnaces are often blanketed to eliminate oxygen because of oxygen's tendency to react with certain metals at high temperature. Other metallurgical applications requiring oxygen-free conditions/nitrogen blanketing include:

• neutral hardening
• carbonizing
• carbon nitriding
• tempering
