Stainless steel and H2O2

I am a "garage inventor" and need to know what happens to stainless steel tube exposed to H202 for long periods of time. This relates to a transfer system I am thinking of constructing.

What grade of stainless steel are you using, 316? hydrogen peroxide is a fairly strong oxidizer, of course; but it should not harm the 316 ss if it has been passivated prior to use to be sure all free iron is off the surface and you have formed a good chrome oxide layer.
