Magnetic Stainless for Spring?
Magnetic Stainless for Spring?
(OP)
Hi All,
Can anyone tell me what grade of stainless steel can be used for a spring (curved spring washer) and will have magnetic properties?
Thanks!

300 series s.s. will likely be weakly ferromagnetic after cold forming, 302 ss is an example. These can typically be rendered non-magnetic again with suitable heat treatment, but may soften as a result.
Some (most?) precipitation-hardening grades will be magnetic, 17-4 PH is an example.
Google for data sheets.

All of the PH stainless alloys are strongly ferromagnetic after aging to high strength.
You could use a cold rolled duplex stainless (S32205) if you needed better corrosion resistance than any of the above. Not quite as high of strength, and not fully ferromagnetic, but close.

There is definately a premium for their steel, they do provide large amounts of data, and if you are not looking for their performance advantages, common production grades will work fine... 420, 17-7, 301 (spring temper) are all good for curved spring washers that need to be magnetic.

Never measured permeability, etc, but cold worked 316 is not easy to differentiate from carbon steel with a strong magnet- that's what I mean by ferromagnetic.

You probably mean bellevile spring.
