UltraGlow® Gas Nitriding

Improve the corrosion and wear resistance in your steel parts with all-over gas nitriding coverage--even inside bores and holes!


The Gas Nitriding Process

UltraGlow® Gas Nitriding is a case-hardening process whereby nitrogen is diffused into the surface of a solid ferrous alloy by holding the metal at a suitable temperature in contact with a nitrogenous gas, usually ammonia.

Benefits of UltraGlow® Gas Nitriding:

  • Extends part/tool life
  • Adds abrasive wear
  • Adds performance, fatigue strength and endurance
  • Enhances surface lubricity
  • Reduces erosion
  • Increases material flow in molds and dies
  • Improves corrosion resistance
  • No post-process machining
  • Improves wear resistance
  • Minimal growth/distortion
  • Precise and versatile
  • Phase controllable compound zone (or white layer)
