Scope: This standard specifies requirements for black oxide films on iron and steel, including cast iron, wrought iron, carbon steel, low alloy steel, and stainless steel. Black oxide film can be used to reduce friction between sliding surfaces or bearing surfaces, or for decoration, or to reduce light reflection. This film can be used where a black surface is required with or without additional anti-corrosion treatment; even with additional anti-corrosion treatment, only very limited corrosion protection performance can be obtained under mildly corrosive conditions. This standard does not specify requirements for the state, processing and surface roughness of the substrate before black oxidation.
