ABSTRACT:
This invention describes the melting of Fe-Mn-Al Alloys and includes production methods such as non-continuous casting, continuous casting, hot forging, hot rolling, cold rolling, surface finishing, and heat treating. Products produced using one or more of the above said methods include case ingot, billet, bloom, slab, cast piece, hot-rolled plate, hot-rolled coil, bar, rod, cold-rolled strip and sheet, and hot-forged piece. The said alloys consist principally of by weight 10 to 35 percent Mn, 4 to 12 percent Al, 0 to 12 percent Cr, 0.01 to 1.4 percent C, 0.3-1.5 Mo, 0.1-1% S, a small amount of Cu, Nb, V, CO, Ti, B, N, Zr, Hf, Ta, Sc, W, and Ni, and the balanced Fe.
