JFE and ThysseKrupp develop multiphase steel
JFE Steel Corporation and ThyssenKrupp Steel AG of Germany have developed a new multiphase steel for automotive applications. It has a minimum strength of 780 megapascals (MPa), similar to that of the advanced ultrahigh-strength steels CP-W 800 from ThyssenKrupp Steel and NANO 780 from JFE Steel. But with up to 40 percent higher elongation compared to conventional 780MPa HSS steel it possesses significantly improved forming properties. Initial components made of the new material confirm its advantages. The two companies have jointly filed a patent on the newly developed material.
