This method must not be used on critically heat-treated parts such as receivers, slides or springs. Black oxide provides minimal protection against corrosion, unless also treated with a water-displacing oil to reduce wetting and galvanicaction. True gun bluing is an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite (Fe3O4), the black oxide of iron. There are many other methods of hot bluing. These panels are also a great choice for those who live in coastal areas or those who regularly have bad weather.

Onetouch All blued parts still require oiling to prevent rust. Instead of applying the acid solution directly to the metal parts, the parts are placed in a sealed cabinet with a moisture source, a container of nitric acid and a container of hydrochloric acid. Then loose oxide was carded (scrubbed) off, using a carding brush or wheel. Residential or commercial options are available, and are built to your specific needs.

However, rust bluing small areas often match, blend, and wear better than any cold bluing process. A non-linear resistance property of the blued steel of razor blades, foreshadowing the same property later discovered in semiconductor diode junctions, along with the ready availability of blued steel razor blades, led to the use of razor blades as a detector in crystal set AM radios that prisoners of war often built during World War II.[2]. Our products include post-frame buildings, pole-barns, and metal-framed buildings.
