Yes, but high grade austenitic steels with Ni added will generally have a
significanly lower magnetic permeability than the cheap Cr-only stainless
steel grades such as 430, which is very magnetic (commonly used in solenoid
plungers, cheap outdoor "stainless" grills, etc) and WILL rust.

The "magnet test" may not be foolproof for a variety of reasons, but would
certainly seem to have some validity.
