Electrically conductive black finish for steel?
Hello, I would like to know the different options available for treating cold-rolled steel to give it the following properties: 1. electrically conductive finish 2. visually black 3. corrosion (rust) resistant 4. at least somewhat scratch resistant.Matt Kowitt

It depends on how conductive is conductive, but there are numerous options including black chrome plating, black nickel plating, zinc plating with black chromate, and zinc-iron plating with black chromate. A black oxide coating would have very limited corrosion resistance.
