GAS SOFT NITRIDING (GSN)

Gas Soft Nitriding (GSN) is a thermo-chemical treatment that involves diffusional additions of both nitrogen and carbon to the surface of ferrous materials at a temperature of 1058F. The atmosphere is formed from ammonia gas and endothermic gas consisting of carbon monoxide, nitrogen and hydrogen.

The benefit of the Gas Soft Nitriding (GSN) process is a tough ductile epsilon carbon-nitride phase with other materials and oxides (the compound zone). An additional benefit of Gas Soft Nitriding (GSN) is the creation of the diffusion zone, which contains a much lower concentration of nitrogen in solid solution with the base material.

OVERALL BENEFITS OF GAS SOFT NITRIDING (GSN):

• Wear Resistance
• Fatigue Resistance
• Corrosion Resistance
• Thermal Performance
• Dimensional Integrity
