Nitriding
Nitriding is a thermochemical surface treatment that introduces nitrogen into suitable metal surfaces to improve hardness, wear resistance, and selected fatigue characteristics. It is commonly used for shafts, gears, molds, dies, and precision components requiring a hardened surface with relatively limited dimensional distortion.

Manufacturing overview
Nitriding modifies the surface of suitable steels and compatible alloys through controlled nitrogen diffusion.
Common processes include gas nitriding and plasma nitriding, each offering different process-control characteristics.
Typical applications include precision shafts, gears, extrusion tooling, molds, dies, and industrial wear components.
Suitable materials include nitriding steels, selected alloy steels, tool steels, and compatible stainless steels.
Nitriding is commonly performed at temperatures below those used for conventional austenitizing and quenching.
This can reduce certain distortion risks, although dimensional changes and surface compound-layer formation must still be evaluated.
Important specifications include nitrided case depth, surface hardness, compound-layer thickness, prior heat treatment condition, and required surface integrity.
Buyers should provide material grade, detailed drawings, treatment areas, target hardness, required depth, quantity, and applicable standards.
Quality verification may include microhardness profiling, case depth measurement, metallographic examination, and dimensional inspection.
