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.
