description	An air-cast ultra-high strength stainless steel prepared by combining Si, Cr, Cu, Mo, Ni, Co, W, and Fe, wherein the steel has a yield strength of greater than 1.482 N/mm 2 , a tensile strength of greater than 1.654 N/mm 2 , and an elongation of greater than 6 percent. In a preferred embodiment, the air-cast ultra-high strength stainless steel includes at least one ingredient selected from the group consisting of C, V, Mn and mixtures thereof. The steel comprises up to 0.08 percent by weight C, in the range of from 0.3 to 1.5 percent by weight Si, in the range of from 9 to 13 percent by weight Cr, in the range of from 0.3 to 3 percent by weight Cu, in the range of from 2.5 to 4.5 percent by weight Mo, in the range of from 4 to 7 percent by weight Ni, in the range of from 7 to 13 percent by weight Co, in the range of from 0.2 to 2 percent by weight W, up to 0.5 percent by weight V, and a remaining amount Fe.
