Heat resisting material
From advanced technology to daily necessaries
The heat resisting material of Nippon Koshuha Steel is in the baseof the society.
The heat resisting material is a base of the high technology that supports the next generation like the aviation space industry and the atomic industry, etc. Nippon Koshuha Steel is delivering the high quality heat-resistant materials that stand high temperature and high pressure, and that have corrosion resistant, toughness, and workability. Heat resisting materials processed to forgings, bars, and wire rod can be widely used for parts such as automobiles, ships and vessels, chemical equipments, and precision machineries.
