The affect of annealing on Permeability

The affect of annealing on Permeability

The affect of annealing on Permeability

Does anyone have any quantitative data on how annealing affects permeability for low carbon steels? Perhaps some B-H curves before and after annealing? I'd like to get an idea of how much is to be gained by annealing.

RE: The affect of annealing on Permeability

Do a search within this forum using anneal as the search term, I found 69 results. Not all of them will apply exactly to your question, but it should help.

RE: The affect of annealing on Permeability

I have some sample data for 12L14 that the maximum permeability increased by a factor of 2.4. The effect of the annealing is going to vary tremendously depending on the condition of the unannealed material. In my case I think it was cold drawn bar so heavily cold worked.


The Help for this program was created in Windows Help format, which depends on a feature that isn't included in this version of Windows.

RE: The affect of annealing on Permeability

Thanks for the information. Yeah, right now our material core specification calls out QQ-S-637, which is a Cold Finish spec. I would assume cold finishing without annealing would substantially reduce permeability.
