Plating application question / recommendation 

+

Plating recommendation.

I am looking for a recommendation on what type of plating would meet the enclosed "wish list" Application is a small stamping (40,000 per month) made from low carbon steel.

"Wish List"

Adheres very well to low carbon steels (1008, 1010, 1018) and different grades of magnetic temperature compensation material (TC30, TC32 etc)

Oxidation protection even in harsh environments

Non magnetic (definitely not Nickel !)

Very good thermal conductivity

High resistance to cracking or flaking even if the steel that it is adhered to is being bent or otherwise worked

Scratch resistant

Tolerates heat up to 250+ Deg C

Plating/Surface treatment process does not change magnetic performance of carrier

Thin, preferably (a lot) less than 0.5 mil thick

Non-toxic (final product)

Cheap

Specific to APPI Std. Parts

Very good electric conductivity

Low surface roughness

Ability to be soldered to with most regular solder types

The answer you are looking for could be a nickel alloy. High Phosphorous electroless nickel meets most of your wish list, non-magnetic, withstand heat etc.
