Corrosion resisting material
Achievement of various characteristics in addition to corrosion resistance Nippon Koshuha’s corrosion resisting materials that came into existence by original technology.
Advanced corrosion resistance is requested from the materials that supports a present technology like electronics and the chemical industry, etc. It is Nippon Koshuha’s corrosion resisting materials to respond such a request from the front. It is materials that have corrosion resistance to various corrosive environments, the mechanical property and the physical property. The application to a wide usage such as parts of the food industry device, the chemical plant, and the electronic equipment is possible.
