If the properties of mild steel are similar to 430 stainless and you are interested at low H then yes heat treatment is definitely worth doing. In the past I have found post machining heat treatment to be necessary for high speed solenoid valves where calibration is done by inductance measurements.

The idea was to use a wound core of something other than the conventional silicon steels and obtain the desired properties through an annealing process. Prototypes were made but the project never got off the ground. I suggest you do a patent search on the U.S Patent Office web site. This could possibly give you some insight as to what has been attempted. -----Original Message----- From: martin_siebert_timmer [mailto:siebertm@xxxxxxxxxxxxx] Sent: Wednesday, March 20, 2002 5:51 PM To: femm@xxxxxxxxxxxxxxx Subject: [femm] Re: Metals Hi Eric, Heat treating with the objective to enhance magnetic properties is an interesting subject. One of the best references on this subject I have come across is: Ferromagnetism by Richard M. Bozorth, IEEE Press ISBN o-7803-1032-2 It is not cheap but well worth it! You can order it online if I am not mistaken - through IEEE.org Other than heat treating, it also deals will Alloying, Stress and Magnetistriction, Temperature and Curie Point to name a few. A very comprehensive text.
