Introduction ■Characteristics of Titanium Titanium, which was found in the 1790s, is the 4th most abundant practical metal existing in the upper crust of the earth. It has taken a long time before an industrial refining process for titanium was reached to completion, and not until 1946 did industrial production of this new metal, titanium begin. The metal was adopted for aerospace applications for the beginning, owing to its specific strength. And then, the demand for titanium, which also has outstanding corrosion resistance, began to increase markedly for such applications as Chemical industries and Electric Outstanding power generation. Today, titanium is a well-known material for its character from aesthetic and for environmental and Light corrosion biological conformity. Titanium, which has excellent physical properties and is friendly to the environment, meets weight resistance Titanium has superb contemporary needs from the world and has a great potential for an expected growth in the future. Titanium has seawater corrosion NIPPON STEEL, which was founded in 2012, as a world top-class comprehensive producer of titanium mill a specific weight resistance and hence is of 4.51, about 60% products, supplies its high-function, high-quality products and services to the customers by utilizing the best ideal for parts used in that of steel. effectiveness of the consolidated management resources of the new corporation and the specialized expertise of the seawater. companies. Based on the results of basic studies of titanium which has been obtained for many decades, with its more strengthened organization and staffs of research and development, we continue R&D for various fields of titanium application, such as Chemical industries, Electric power generation, Seawater desalination, Civil engineering, High Architecture, Automotive, Consumer appliances, and Aerospace industries, etc. We are also developing new Production of Titanium Good strength workability applications of titanium actively aiming to customers’ needs. Products by NIPPON STEEL NIPPON STEEL is to pursue the infinite potential of the contemporary metal, “Titanium”. Titanium is Titanium is comparable in as workable NIPPON STEEL has R&D capability and quality control strength to steel. as steel. systems nurtured in its steelmaking operations.
