Abstract

DUAL-TEN 590 (UTS 590 MPa, or 86 ksi) is a dual-phase steel for the automotive industry. Dual-phase steels are most commonly used in structural applications where they have replaced more conventional HSLA steels. They offer a great opportunity for part weight reduction. The improved formability, capacity to absorb crash energy, and ability to resist fatigue has driven this substitution. Applications include front and rear rails, crush cans, rocker reinforcements, pillar reinforcements, cowl inner/outer, back panels, cross members, bumpers, and door intrusion beams. This datasheet provides information on composition, physical properties, microstructure, and tensile properties as well as fatigue. It also includes information on forming and joining. Filing Code: SA-532. Producer or source: United States Steel.
