HIGH DUCTILITY STEEL ALLOYS WITH MIXED MICROCONSTITUENT STRUCTURE

摘要

This disclosure deals with steel alloys containing mixed microconstituent structure that has the ability to provide ductility at tensile strength levels at or above 900 MPa. More specifically, the alloys contain Fe, B, Si and Mn and indicate tensile strengths of 900 MPa to 1820 MPa and elongations of 2.5% to 76.0%.
