Permeability attainable in cold-worked Austenitic Stainless Steel
Permeability attainable in cold-worked Austenitic Stainless Steel
(OP)
A device using a Hall effect sensor and magnet for position sensing also uses springs made from type 304 Stainless steel, which are sufficiently cold worked to be attracted to a magnet. My task is to perform magnetic FEA to characterise the device, and my questions are twofold:
First, what is the limit of relative permeability that is attainable through cold working of type 304 steel, and
Second, is B-H curve data available anywhere for cold-worked austenitic stainless steel?
Enlightenment on these items would be greatly appreciated.
Thanks,
Mike.

If I have 8.5% Ni and 0.08% N2, I can get 120-140 ksi tensile strength with <1.05 easily.
If the Ni is 8.0% and the nitrogen is 0.05%, I can draw to 150ski min and have at least a perm of 2.
I don't think that there is a generic answer for you.

Corrosion, every where, all the time.
Manage it or it will manage you.
