Gas Nitriding Nitreg®

Gas nitriding is a thermochemical surface treatment process that enhances the performance and service life of critical components by diffusing nitrogen into the material surface. Unlike conventional hardening methods, gas nitriding improves surface hardness, wear resistance, fatigue strength, and corrosion resistance while maintaining dimensional stability and minimizing distortion. The process is widely used across aerospace, automotive, energy, tooling, and industrial manufacturing applications where component reliability and longevity are essential.
