Nitriding steel represents products which are case-hardened to increase the hardenability of the product significantly.
The characteristics of nitriding steel, common in low-alloy steel grades, include improved hardness, fatigue strength, and wear resistance. The process consists of three treatment methods - gas, plasma and salt bath nitriding.
- Harder surface layer
- Increased wear resistance
- Superior fatigue strength
- Strong core
Nitriding is a heat-treatment process where nitrogen or ammonia is introduced and diffuses with the elements in the material to form hard metallic nitrides on the material's surface. The resulting process creates an engineering material with increased hardenability after heat treatment.
The case-hardened material is typically thin (only a few microns), but the material characteristics significantly change.
