Would 17-4ph h900 resist snapping better that harded D2 TS?

  1. Sep 12, 2015 #1
    Continually breaking a 0.236 dia. pin wrench, tightening a threaded collet-closer in high speed production application. Both ends of 1/2" D2 tool steel, turned down to create pin wrench, one end is bent at 60 degree angle, to allow an awkward reach sometimes necessary. D2 TS is then hardened & tempered. The 0.236 pins snap. Believe using 17-4 ph stainless steel, h900 would eliminate snapping. Can anyone comment?
