Can stainless steel be turned black? The act of turning stainless steel black is called “bluing.” Bluing chemicals used to require a heat source to work. Because heating these chemicals was bad for the environment, new chemicals have been developed to turn stainless steel black or brown.
How can I make my stainless steel hardware black?
Can you chemically blacken stainless steel? Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance and to minimise light reflection.
Can you blacken stainless steel with heat? Heat Blackening
Several methods have been used to darken stainless steel using heat. All decrease corrosion resistance by leaving a heat tint or scale on the surface, which prevents the formation of the usual protective passive film. None produce a consistently uniform dark appearance.
