    Dies for 304 Stainless

    I need to thread 350 3/8" 304 stainless rods about 1" standard course thread.
    I can't find any dies other than high speed steel and I don't know if they will hold up for this many. Do they make special dies for stainless? I will be using
    a ridgid 400 pipe threader. Any help will be greatly appreciated!

    Pipe threader with rigid die should handle this acceptably.
    We normally CNC turn stuff like that.
    I frequently do .5" 304 with 12" threaded. It flexes too much in the lathe to fully thread, so we CNC 80% - 90% depth and use the Rigid to finish to size.

    The 1/2-13 IS too much for the threader (I don't what model threader we use for this, but it is the big one with the opening dies).
