Metal Technology Engineering offers expert gas nitride hardening on a sub contract basis. This service is designed to improve ferrous components’ durability, performance, and longevity. With decades of experience in advanced heat treatment solutions, we help manufacturers and engineers across industries achieve optimal wear resistance, surface hardness, and fatigue strength for critical parts.
Gas nitriding is a low-distortion, thermochemical surface hardening process that introduces nitrogen into the surface of steel at relatively low temperatures, typically around 520°C. This process leads to the formation of hard nitride compounds that significantly improve the mechanical properties of the treated parts without compromising their core structure.
Gas nitride hardening is a case hardening technique that diffuses nitrogen into the surface layer of a ferrous metal part. The nitrogen reacts with alloying elements like chromium, molybdenum, vanadium, and aluminium to form hard nitrides that enhance wear and fatigue resistance.
The treatment forms two distinct layers:
For applications requiring additional properties, a carbon-donating gas can be introduced in a variation of the process known as gas nitrocarburising.
Choosing gas nitride hardening provides several performance benefits for components exposed to heavy mechanical and thermal stress:
Our gas nitride hardening services are widely used across automotive, aerospace, tooling, and general engineering sectors. Typical components treated include:
Gas nitriding is best suited for steels containing nitride-forming elements, including:
Pro Tip: For best performance, parts should be hardened and tempered before nitriding, ensuring the core structure supports the enhanced surface properties.
