Non-magnetic Stainless Steel?

Any metallurgists out there? I assume that this magic feat is done by the trace elements added to produce various kinds of steel, but I thought that ALL steel was magnetic. Does anyone know which trace elements and the different proportions of these trace elements that can transform regular stainless steel into non-magnetic stainless?

I am not up on the tecno data, but I thought all stainless steel is non-magnetic.

I believe it has to do with the chromium content, but I am not sure what percentage of chromium is required.

All steel is magnetic up to a certain degree, but some stainless is less magnetic.

Do a google:

Basically, even the less magnetic stainless steels can become magnetic once they are worked.
