Heat Treating Safety with A Nitrogen Generator

Heat treatment of metals requires the presence of N2 gas for both safety during the process of treatment and quality of the final product.  Nitrogen is used to quickly cool a metal that has been heated to extreme temperatures in order to alter its properties, often for conditioning and hardening.  It is also used for blanketing purposes in order to provide a safe and neutral atmosphere for treatment.

Metals and alloys are heat treated to enhance their strength and build up their resistance to wear and corrosion.  Metals can also be tempered to increase flexibility or to relax stresses.  Heat treatment application results in high quality parts that can be supplied at competitive prices, especially when Nitrogen gas is generated on-site for blanketing purposes to reduce oxidation and absorb hydrogen.

A Nitrogen Generator is effective at producing high purity N2 gas on demand using a simple and reliable process.  The use of a Nitrogen Generator in heat treatment of metals streamlines the process, making it more safe, reliable, and cost-effective.

There are a number of techniques that can be applied to heat treating metals using Nitrogen gas as a blanketing agent for both safety and quality concerns and/or a forced air cooling agent for heated metals.

• Quenching
• Tempering
• Annealing
• Hardening
• Galvanising
• Normalising
• Sintering
