Method for coloring stainless steel

Abstract

The present disclosure relates to a method for coloring a stainless steel object. The method includes a mechanical step of abrading the surface of a stainless steel object to be colored, slowly heating the object to a predetermined temperature, slowly cooling the object to a predetermined temperature, cleaning and then sealing the object for use. Color is controlled by the degree of abrasion imparted on the stainless steel during the mechanical process. Coarse abrasion results in blue colors while fine abrasions result in copper, gold and bronze colors. Once abraded, the stainless steel is heated slowly in a convection oven to approximately 940° Fahrenheit to fix the color. The device is then slowly cooled to approximately 125° Fahrenheit which stabilizes the stainless steel for use. After cooling the stainless steel can be cleaned with phosphate and sealed using conventional powder coating methods.
