    Ferro Niobium

    Melting Range 1500-1550ÂșC

    Also called Columbium and used by steel makers as a grain refiner in HSLA steels and as a carbide former in austenitic stainless steels. The alloy is available packed in drums or bags sized 0 x 2mm, 3 x 10mm and 5 x 30mm. The specification is typically Nb 65%min, Ta 1%max, C 0.3%max, Si 0.3%max, Al 0.2%max, S 0.1%max, P 0.1%max.

    Reactor grade ferro niobium is also available for effective control of residual element levels and is particularly useful in superalloy production.
