Black Oxide Steel & Stainless Steel Coatings

Black Oxide on wrought iron, cast/malleable iron, low carbon alloy STEEL. 300-Series, 400-Series, and 17-4 PH STAINLESS STEELS.

Black oxide is a conversion coating formed by the chemical reaction with the iron in a metal to form an protective surface. Oxidizing salts react with the iron to form magnetite (Fe304), the black oxide of iron. It must be impregnated with oil or wax.

Advantages:

No buildup.
Mild corrosion resistance
Improved appearance

A uniform black coating for ferrous metals that is used primarily as a decorative finish; only limited corrosion protection under mild corrosive conditions. Black Oxide coatings should be given a supplementary treatment; (ie. displacement per MIL-C-16773 Grade-3, or protective treatments per MIL-C-16173). For moving parts which cannot tolerate dimensional or physical change; can be used to reduce reflected light.
