Black Oxide Treatment for Stainless
Black Oxide Treatment for Stainless
(OP)
Does anyone know of a Westcoast (preferably WA or OR) vendor that does black oxide treatment of stainless. Or does anyone know any other "tricks of the trade" for coloring stainless steel black? I am speaking primarily of 303 and 304 S/S. I've tried painting (after passivation) but the paint chips off easily. Thanks!

Alternatives if this processor doesn't work out:
1) Black chromium plating. MIL-DTL-14538D CHROMIUM PLATING, BLACK (ELECTRODEPOSITED). Durable & corrosion resistant; often used for solar collectors.
2) Black nickel plating. Thin, goes over a nickel underplating, mostly for optical properties. Can be lacquered.
3) Do-it-yourself room temperature blackening. Not a black oxide, but rather a coating of black CuS or CuSe. Needs a wax, oil or lacquer for protection. Some of the hot black oxide chemical suppliers (see below) also sell, but perhaps the 2 largest US suppliers are EPI & Birchwood-Casey:
