Need non magnetic hard metal coating
2003
RFQ: Hi, we here are in need of a non magnetic material capable of attaining high hardness of around 55-60 Rockwell C. This material should be machinable to a final shape and to be able to get heat treated to this hardness. Could you please let us know if you have information on or this type of material itself? Or, is there a non magnetic coating that could be deposited on steel (by electro plating or similar techniques)? This coating should be as hard as mentioned above (55-60 Rockwell C) and should have a longer life without peeling off.
If yes, please let us know availability, its price, and who sells it.
Thank you very much. I appreciate your help in anticipation.
Thank you and have a great day.

A. How about hard chromium plating? Its hardness is even higher than 65 Rc, it's non-magnetic and can be ground to exact dimensions. When properly plated it will not peel.

A. In addition to hard chrome that would have to be machined to get a uniform deposit, a high phosphorous electroless nickel (which is non-magnetic) could be heat treated to attain the hardness that you require.
