What We Offer


Blackening is a post heat treatment process for materials. The purpose is mainly for aesthetic appearance and to add a mild corrosion resistance layer.  The black oxide layer from the blackening process is magnetite (Fe3O4), which is more mechanically stable on the surface, providing the mild corrosion resistance.
