Black Oxide

What is Black Oxide?

Black oxide is a conversion coating for ferrous materials applied most commonly on steel.  When applied, an attractive black finish is obtained.  The high-temperature black oxide process is essentially a chemical conversion of the steel surface and does not change surface dimensions significantly.
