H&W Global Industries, is one of the few companies in the United States offering black oxide coating for stainless steel. Black oxide on stainless steel produces an essentially dimensionless conversion coating that creates a highly durable black finish with an absorbing oxide layer for oils and waxes.
Black oxide is a unique finish and uses a unique process to develop an effective and cost-effective conversion coating that is used in many coating applications. Black oxide is a five-step process consisting of cleaning, rinsing, black oxide, rinsing, and a supplementary coating or after-finishing. Black oxide coating cannot be used over plated parts; the plating must be removed before the coating is applied.
