If the mounted planer tables have stainless steel covering the aluminum substrate, why doesn't my magnetic dial indicator stick to it? Is the surface NOT stainless steel???

Any insight would be appreciated.

Many stainless steels won't hold a magnet.

according to Peter Eng, a physicist at the University of Chicago, is that different stainless steels contain different proportions of nickel (added to help keep steel from cracking and to allow the addition of more carbon, for strength). More than two percent nickel interferes with what Eng calls iron atoms’ “magnetic moments.”

My stars, you learn something everyday .... even at my age ....

And I thought I knew everything LOL

Thanks Mike!
