Any feedback on the carburized/nitrided bolts regarding bolt life, etc.?
I am aware of the limitations of straight nitriding, which is why I commented on that in my convo with Bill about having a good CH process under nitriding would prevent any possible cracks in nitriding from spreading further.
I would never think it a good idea to forgo CH in favor of straight nitriding.
