I like shiny things. Though standard Black Oxide is set up for steel, it can be done on other substrates including stainless steel, copper, and brass among others. Hot black oxide  for stainless steel is a mixture of caustic, oxidizing, and sulfur salts. The black does two things: it looks a little cooler, and it helps prevent reflections. Black Oxide, like other coatings is used to provide protection to the part, achieve a required appearance or achieve other desired properties. The typical ones being used are classes 1 and 4, for fasteners. Choosing stainless steel as an application over a zinc alloy will depend on a company’s needs. Very good indicator of non-passivation when 304 or 316 fail, though. Black Oxide: Common Failure Causes The conversion technique, as already determined, isn’t a depositing technique. Black oxide failure happens when an ingredient is poorly applied or the process isn’t performed according to an exactingly conferred operational doctrine, but chemical composition isn’t the only factor that’s causing trouble. I’m pretty sure it was the epi black oxide product that we used at my shop to color some stainless parts but It required heating the solution in a hot tank Reply Report Materials: The black stainless steel is available in 304 and 316 stainless steel and offers an attractive finish for general (304) and harsh environments (316).The PVD (Physical Vapor Deposition) surface treatment is quote durable, and is actually harder than the stainless steel surface itself.
