My name is Dennis McGlumphy, and am an electrical engineer.  I'm looking for any information on the magnetic permeability of steel for temperatures from 60 deg. F to 2400 deg. F.
 
If anyone has the answer to the above question, I'd also like information on rooom temperature permeability of steel. Any responses can be sent to nathantoy@hotmail.com. Thank you.
 
I also need this information. please respond at

Hi, I need the information on the magnetic permeability of Nickel-Iron. Can anyone help? Please respond at karatekiddy@hotmail.com .
 
My understanding is that if the steel is in the Austenitic form (face centered cubic structure or gamma phase), the steel will show no ferromagnetic properties.

I hope this helps :-)
 
Dennis and Nate:

You will find info on magnetic permeability at different temperatures in Vol. 1 of the Metals Handbook published by ASM International (formerly American Society for Metals) which is available in most technical libraries. If you have specific questions, you can e-mail me at ftg@gerson.on.ca

Good luck
 
I am making a setting fixture for a capacitor discharge magnetiser. I require for this high permeability steel. I have been told that I need to use 'sweedish iron'. Has anyone heard of this or know what specification of material i require?

"Swedish Iron" is a common name for high-purity wrought iron. It got its name many years ago because Swedish ores were very low in impurities. Any modern soft magnetic wrought iron will offer comparable properties.
