Gas Nitriding

A surface hardening process where nitrogen is diffused into the surface of steel at a high temperature to create a hard, wear-resistant layer without altering the core.

Gas Nitrocarburizing:

Similar to nitriding but introduces both nitrogen and carbon, resulting in improved wear and fatigue resistance with shorter treatment cycles.

Carbo Nitriding:

A case hardening process using a carbon- and nitrogen-rich atmosphere to harden the surface while maintaining a tough core, ideal for wear resistance.

Case Carburizing (Hardening & Tempering):

Carbon is diffused into the surface at high temperatures to create a hard exterior, followed by hardening and tempering to adjust toughness.

Austempering

A heat treatment that involves quenching a metal in a medium (like molten salt) to achieve a bainitic structure, offering high toughness and reduced distortion.
