Magnetic Permeability Measurement of Stainless Steels in Vacuum Chamber Fabrication

M. S. Hong , C. D. Park


We measured the magnetic properties of stainless steels type 304 and 316L to see if those materials can be used for the applications where non-magnetic materials are required. The results show that the relative permeability of samples was greatly increased during manufacturing processes. After full solution annealing, however the permeability could be reduced to less than 1.02. Thus, the materials may be employed in the low-permeability applications.
