  • Publication number: 20190039110
    Abstract: Rather than using a conventional stamping forming process with steels having high ultimate tensile strength and relatively low initial yield, tubular hydroforming techniques are introduced to synergize with BIW part forming, or forming of other load bearing parts. Such steels can have ultimate tensile strengths of greater than 1000 MPa and initial yields of less than 360 MPa In some embodiments, the steels have elongation of at least 40%. Such steels can include retained austenite.
