Magnetism developed by austenitic 304 stainless steel after cold worki
(OP)
Hi¡ everybody:
As we know, austenitic stainless steels show slight to severe magnetism depending on the amount of martensite transformation after cold working. However, I have not bibliography about it, Does any body have some literature to provide me.
One of my customers detected some magnetism on 304 ss (he produces storage tanks and, obviously, he had to roll the sheet), after the rolling operation he detected the magnetism. He is reluctant to believe that asutenitic ss becomes magnetic after forming operations.

Obviously you customer is not doing his home work. The subject covered in various shop and machinists handbooks.
Extensive cold working as well as extensive heat treating can produce a significant increase in magnetic attration especially in 304
If it has iron in it, it is hard to keep it from being magnetic
