カナック Company Profile

Expanding possibilities. Achievements of 4,000 partner companies.

Kanak processing is a gas nitriding treatment using a unique method. The material is held in a heating atmosphere of around 500°C for several hours, allowing nitrogen to diffuse from the surface of the steel and react with metal elements to form a hardened layer. Unlike conventional nitriding treatments, there are very few brittle iron nitride compounds near the surface, and the high compressive residual stress along with a smooth hardness distribution are characteristics of Kanak processing.
