Bending, expansion, and dimensional changes are minimal! Uniform effects can be achieved even with complex shapes and deep holes.
The "Kanak treatment" is our unique gas nitriding process developed in 1985 as a hardening treatment for non-magnetic stainless steel, which was considered difficult at the time. It is a diffusion treatment primarily based on CrN and MoN, significantly improving issues associated with conventional nitriding, such as reduced toughness, dimensional changes, and surface roughness, thereby enabling a wide range of applications. We will expand our treatment lineup to meet the needs of many customers based on this treatment. 【Features】 ■ Low reduction in toughness, with a diffusion layer as the main hardened layer ■ Uniform effects can be obtained even on complex shapes and deep holes ■ Minimal change in surface roughness ■ Little warping, expansion, or dimensional changes ■ Reproducibility of treatment effects through repeated processing *For more details, please refer to the PDF document or feel free to contact us.

Company information
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 and permeate from the steel surface, reacting 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 and smooth hardness distribution are characteristics of Kanak processing.
