Abstract: In this work the magnetic properties of AISI 304L austenitic stainless steel was subjected by using the
magnetic induction with different working frequencies. For this purpose a sheet rolled from 10 to 80
% reduction at 0ᵒC was used. Then, by using Eddy current instrument at frequencies from 50 to 10000
Hz, magnetic behavior was studied. The results were made of two parts: (1) linear part where the
reduction was lower than 10%, more non-magnetic transformation (Ɣ→ɛ) occurs in this region, (2)
Exponential Rise to Max curve where the sudden increase in formation of ά-martensite (Ɣ→ά) and
disappearing of ɛ-martensite occurs, lead to a sharp increase in permeability. Also an obvious relation
between parameters of the function that fitted with it and structural changes was found.
