Sorting Stainless steel Bearings from Chrome Steel ones

Hello Friends

We have accidently  mixed a large quantity of our surplus Stainless steel Miniature Ball bearings with many Chorme steel types.

Is their any simple home test by which we can seperate the 2 types in a way we do not damage our stocks

The dimensions are the same only the material is different.

SOS here..please help

Thanks for reading this guys

RE: Sorting Stainless steel Bearings from Chrome Steel ones

Assuming the stainless steel type bearings are austenitic a simple magnet should seperate them. However the chrome steel bearings may need to be demagnetized after seperation.

thanks for your reply
I tried that and found both stainless steel bearings and the chrome steel attract to the magnet. I used the copper sulphate solution to differntaite them but that would ruin all the bearings

RE: Sorting Stainless steel Bearings from Chrome Steel ones

It seems that your stainless steel berarings are not austenitic stainless steel. You should try PMI (Positive Material Identification).
