This disclosure relates to weldability of steel alloys that provide weld joints which retain hardness values in a heat affected zone adjacent to a fusion zone and which also have improved resistance to liquid metal embrittlement due to the presence of zinc coatings.

Welded advanced high strength steel

This disclosure is related to high yield strength steel where mechanical properties, such as elongation, ultimate tensile strength and yield strength in a sheet are maintained or enhanced via thermal treatment optionally provided during a galvanization coating operation.

This invention relates to prevention of delayed cracking of metal alloys during drawing which may occur from hydrogen attack. The alloys find applications in parts or components used in vehicles, such as bodies in white, vehicular frames, chassis, or panels.

Delayed cracking prevention during drawing of high strength steel

This disclosure is directed at methods for mechanical property improvement in a metallic alloy that has undergone one or more mechanical property losses as a consequence of forming an edge, such as in the formation of an internal hole or an external edge. Methods are disclosed that provide the ability to improve mechanical properties of metallic alloys that have been formed with one or more edges placed in the metallic alloy by a variety of methods which may otherwise serve as a limiting factor for industrial applications.

Weldability improvements in advanced high strength steel

This disclosure is directed at methods for mechanical property improvement in a metallic alloy that has undergone one or more mechanical property losses as a consequence of shearing, such as in the formation of a sheared edge portion or a punched hole. Methods are disclosed that provide the ability to improve mechanical properties of metallic alloys that have been formed with one or more sheared edges which may otherwise serve as a limiting factor for industrial applications.

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%.
