STAINLESS STEELS - JFEスチール株式会社

1 STAINLESS STEELS . Setting the Standard for Tomorrow JFE STAINLESS Steel JFE Steel is a brand new company that has been established in April 2003 as a result of the consolidation of steel divisions of Kawasaki Steel and NKK. Although the company is newly born, we already have a history of 40 years in production of STAINLESS steel. During the years, demand for STAINLESS steel has shown a tremendous increase and at the same time application has expanded to numerous fields from construction, kitchen equipment, automobile parts to electronic components etc. because of the reliability and attractiveness of the material. As an integrated STAINLESS steel producer, JFE produces STAINLESS steel from steel making stage, to hot and cold rolling. Responding to the diversifying needs of the market, high quality is ensured to every product through production in our state of art production facilities under latest process technology. In the recent years, as the leading company in production of chrome type STAINLESS steel, we pride ourselves on becoming even more capable to meet various customer needs including higher corrosion resistance and formability with our wide variety of chrome type STAINLESS steel lineup, as a result of our strategy to concentrate all of our management resources into production and development of chrome type STAINLESS steel.
