    Any of the Black fluxes like Handy Flux Type B-1 or Harris Stay-Silv
    Brazing Flux (Black) or any other boron modified flux. They are
    basically white paste flux with boron powder added. The boron
    extends the fluxes ability to dissolve oxides for a longer period of
    time and at higher temperatures. They are recommended when working
    with alloys that have high chromium content. Chromium is what makes
    stainless steel stainless so the black fluxes work great on
    stainless. 

    There is a good web page with info on black flux at
    http://www.carbideprocessors.com/Brazing/book/13.htm
