ALPOLIC/fr TCM (Titanium Composite Material, hereafter TCM), a composite panel of titanium, resin and stainless steel of Mitsubishi Chemical Infratec Co.,Ltd. (Mitsubishi Chemical Infratec), has been adopted for the roof of the Yangtze River International Conference Center. ALPOLIC/fr TCM contains the designing titanium TranTixxii of Nippon Steel Corporation (Nippon Steel) and NSSC220M, a high corrosion resistance ferritic stainless steel sheet of NIPPON STEEL Stainless Steel Corporation (NSSC).
NSSC220M is stable in price since it is resource-saving stainless steel that contains little nickel. In addition, it has higher corrosion resistance than SUS316 (austenitic stainless steel), which is a generic-grade of high corrosion resistance stainless steel. Furthermore, NSSC220M is almost the same as titanium in linear expansion coefficient, meaning that this stainless steel material prevents panel distortion caused by temperature and environmental changes.
Nippon Steel Group will continue to pursue the best technologies in the world as well as the manufacturing capabilities and continue to contribute to the progress of society by developing manufacturing processes and providing excellent products and services in conformance with the sustainable development goals (SDGs) adopted by the United Nations.
