Implications of adding selective Gold over Stainless Steel 301-1/2 hard

November 4, 2008

This is Carlos Velazquez & I work in Mexico for a company which stamps material for the Automotive Industry. A customer is asking for a quote which implies to have a strip of SS 301 - 1/2 hard (Thickness = 0.020") preplated with selective Gold (15 micro in of Gold over 50 micro inches of Sulphamate Ductile Ni) but I would like to know if, based on the electrical properties of the SS, is possible to get the achieve the process and what are the implications of doing it.

Thank You in advance for your support & help !

Gold over sulfamate nickel over stainless steel. It is totally possible. You need to activate the SS substrate. Some experts recommend a high all chloride bath called Woods strike, others would prefer a sulfamate strike. Once active you can plate anything on top.
