"Removing magnetism from stainless steel 304"
Q. I want to remove magnetism from stainless steel 304 Products after they are cold worked.
factory - Pakistan
Q. Please tell me the ways to get rid of magnetic property of my cold worked stainless steel 304 hinges, as my customers are not in the sense of magnetic property in steel.
Please reply to me soon by mechanical means.

A. If your parts are magnetic, i.e. they will stick to a piece of iron, then you can run them through a degausser. That electrical instrument will expose the parts to alternating polarity, continually decreasing magnitude magnetic fields. This will remove residual magnetism.

A. If you heat it, even with a torch, and or stress relieve cold formed 300 series, it will remove the magnetic properties.Dan Magalich

Q. How to remove magnetic properties from ss 304 screws, washers & spring washers?huzefa sabuwala

A. Hi, Huzefa.
As you see, we appended your inquiry to a thread which already answers it. You can remove true magnetism (that is, where the screws attract iron) with an electrical degausser. But you can remove ferromagnetism (that is, where a magnet attracts the screws) only through re-heating to change the crystal structure as suggested by Dan. Good luck.

Q. I am trying to remove the magnetic attraction of cold worked 304 SS so that it is much less or not affected by a induction coil at all. Will this work as well?Marvin Lane
