Many standards don't recommend UT on austenitic steel, some of them don't allow to use this method.
Austenitic steels have large grains and this crystallographic structure leads to low ultrasonic permeability
But this doesn't mean that it's impossible. There are some studies on this problem and they have some solutions.
If you use UT, note that the methods's sensitivity will be low.
I recommend 2 MHz (or 1 Mhz for very thick materials) probes
I can give detailed info if you decide to use UT
