Challenging the Future
Kobelco Steel Tube developed seamless tubes for use in the MONJU fast breeder reactor built in Japan. Made of modified TP316 stainless steel, these tubes feature excellent creep strength and resistance to swell. New facilities for the mass production of these tubes were completed in 1987. In addition to these products, new ferritic steels, including one strengthened by oxide dispersion, are also being developed.
Example of application
・For space aircraft
・For Nuclear power plants
・For semiconductor equipment
・For OA equipment
・For Machinery parts
