316L & XM-19 Stem material

[Isha90]

For a Gate Valve Customer asking A182 F316L Stem material instead of A479 XM-19, I want to know if there is any disadvantage in using XM-19 over 316L in process & power industry please,

D.S., wrong comparison.
In this case the XM-19 (Nitronic 50) will be as good or better than 316 in every way that I can think of.
Stronger, more gall resistant, tougher and at leas equal corrosion resistance.
