NP Pionite Treatment is our own unique technology,
capable of hardening the surface of austenitic stainless steels
such as SUS 316[AISI type 316] while maintaining resistance to corrosion.
Using activation treatment technology, a carbon solid-solution diffusion
treatment maintains a tough and beautiful stainless steel surface.
This NV Pionite Treatment is now in widespread use in various fields,
including industrial products and household-related products.
