304 vs 410
304 vs 410
(OP)
Is there an inexpensive way to tell 304 from 410 SS fasteners. As both are magnetic due to work hardneing I am having trouble with a simple test. In my application a rusting nut would be a disaster and I have to ensure 304SS.
Thanks R.Webb

If you have commingled large lots it will be quite difficult to separate the two types of fasteners with a magnet as 304 screws can be very magnetic. We had lots commingled that weren't discernible by hand and had to separated by machine.

Annealing the 304 nut with lock washer I found the nut to be 304 but not the lock washer. Will incorporate this test in receiving prior to releasing to production.
this has been very useful to me and I hope others!
