Discussion on magnetic properties of cold working

1. In general, the 300 series of stainless steel austenitic structure, although the magnetic properties are not explicit, but the cold working of processing, they may be transformation as a significant magnetic field of martensite organization,

(1)austenitic organization of stability degree to reduce (alloy design),

(2)cold working amount increased, they will generate more martensite organization,

So that the magnetic relative increase,
This part of the magnetic and working stress, the opportunity to be fully solid solution annealing (heating after quenching) to eliminate.
2. Effect of cold working on stainless steel of austenitic:
