  • High formability dual phase steel
    Patent number: 10808293
    Abstract: To improve the formability of dual phase steels, the martensite phase is tempered. It may form a ferrite-carbide structure. The tempering step occurs after martensite has been formed in the dual phase steel. The tempering step can occur in a box annealing step or it can be performed in a continuous fashion, such as on a continuous annealing, continuous tempering heat treating, or continuous coating line. The tempering step can further comprise a temper rolling on a temper mill after the heating step.
    Type: Grant
    Filed: July 15, 2016
    Date of Patent: October 20, 2020
