Abstract DUAL-TEN 780 (UTS 780 MPa, or 113 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 high-strength low-alloy (HSLA) steels. Applications include front and rear rails, crush cans, rocker reinforcements, pillar reinforcements, inner and outer cowl, back panels, cross members, bumpers, and door intrusion beams. This datasheet provides information on physical properties, tensile properties, and bend strength. It also includes information on forming and joining. Filing Code: SA-535.
