WHAT IS THE 304 STAINLESS STEEL NON MAGNETIC TOOL ?
Only stainless steel with pure austenitic structure has no magnetism.
Such as: 304, 316 and other stainless steel (but usually these austenitic stainless steels need to be cold-processed, in the process of processing there will be austenitic structure precipitation part of martensite structure, so the material will also have the phenomenon of weak magnetic field).
Ferrite (mainly 430, 409L, 439, 445NF, etc.) and martensite (represented by 410) are generally magnetic.
