Magnetic permeability of Carbon Steel

[pariasattari]

Hello,

I need to find out the magnetic permeability of Carbon Steel with temeperature (from T=20degC to the Curie point). I appreciate if you share any information you might have or can introduce a reference.

Thanks.

Permeability is not a constant. Besides varying with temperature, it's a function of the applied magnetic field H as well as the composition and heat treatment of the steel. Carbon steel covers a really wide range of materials.

Have you looked at any suppliers web sites? Those that produce very low carbon "electrical irons" will have extensive data. Try Carpenter and CMI for starters. You won't find much for higher carbon levels.
