NEW CLASSES OF NON-STAINLESS STEELS WITH HIGH STRENGTH AND HIGH DUCTILITY
摘要
The present disclosure is directed and formulations and methods to provide non-stainless steel alloys having relative high strength and ductility. The alloys may be provided in sheet or pressed form and characterized by their particular alloy chemistries and identifiable crystalline grain size morphology. The alloys are such that they include boride pinning phases. In what is termed a Class 1 Steel the alloys indicate tensile strengths of 630 MPa to 1100 MPa and elongations of 10-40%. Class 2 Steel indicates tensile strengths of 875 MPa to 1590 MPa and elongations of 5-30%. Class 3 Steel indicates tensile strengths of 1000 MPa to 1750 MPa and elongations of 0.5-15%.
