Nitriding is a highly specialized surface hardening treatment that produces a thin but high hardness case on a wide variety of steels. The significant advantage of nitriding over other surface hardening processes is that the case hardness is developed without quenching and subsequent distortion issues. Finishing operations can be eliminated or minimized.
Utilizing the Nitreg® Potential-Controlled Gas Nitriding technology Peters’ Heat Treating provides a modern approach to nitriding capable of meeting the metallurgical requirements of all nitriding specifications. Many of our customers have chosen Nitreg® as a replacement for carburizing, ion nitriding or salt bath nitriding, enjoying the invaluable benefits of no distortion and the elimination of costly finish grinding.
Nitride surfaces are extremely wear resistant providing good lubricity with anti-galling properties. Nitriding also produces extended fatigue life and improves corrosion resistance. Other advantages include resistance to softening by temperatures up to the processing temperature (approximately 950F-1025F).
Our FNC/ONC process provides a black finish similar to that of Black Oxiding while in most cases meeting 300-hour salt spray requirements.
Processing benefits include:
- Control of case depth
- Control surface hardness
- Control of compound layer
- No distortion
