Advanced HSLA Steels for Automotive Use

摘要：

Characteristic HSLA steels for automotive use are introduced in which both of precipitation and microstructure is controlled to obtain suitable mechanical properties. For outer panels such as fender, the combination of low yield strength, high tensile strength and deep-drawability were realized by controlling the distribution of NbC and precipitation free zone. The other steel, developed for chassis parts such as lower arm, utilizes extremely fine interphase precipitation to obtain high yield strength and excellent hole expansionability. Both steels have contributed to the reduction of weight in car body.
