The applicable steel grades have dramatically expanded! It is possible to design nitride layers rich in flexibility to meet specific applications!
We would like to introduce the features of our unique nitriding process, "NV Nitriding," which combines surface activation treatment (fluorination treatment) and gas nitriding treatment. Processing is possible over a wide temperature range from low-temperature treatment in the late 300s °C to up to 600 °C. We can select processes according to your product specifications. Additionally, we can achieve fine atmosphere control, such as processing at low nitrogen potential. 【Features】 ■ Dramatically expanded applicable steel types ■ Processing is possible over a wide temperature range from low-temperature treatment in the late 300s °C to up to 600 °C, allowing for process selection according to your product specifications ■ Fine atmosphere control, such as processing at low nitrogen potential, is possible ■ Flexibility in designing nitriding layers to accommodate specific applications, such as "for forged molds" *For more details, please refer to the PDF document or feel free to contact us.

Company information
Air Water NV Corporation is a company located in Amagasaki City, Hyogo Prefecture, that specializes in metal surface treatment. NV nitriding is a metal surface treatment technology that enhances the wear resistance of sliding machine parts and similar components. It protects the metal by allowing nitrogen atoms to penetrate the metal surface and create a hard layer. By combining gas activation treatment and gas nitriding, it achieves a high-performance nitriding layer through powerful nitriding capabilities and control technology. Additionally, it enables low-temperature treatment and accommodates various processing needs.
