Why does SH3501 specify that MT and RT are not to be used for carbon steel and stainless steel welds?

MT is not performed because austenitic stainless steel is non-magnetic and cannot be detected by magnetic particle testing

Should RT and UT be used?

Yes, but why can’t MT and PT be used? It’s probably because only surface defects can be detected; deep defects cannot be identified
