First-base carbon steel is black as it is produced directly by steelworks, and therefore in the presence of calamine and iron oxide. The uses of black steel are varied and range from purely structural and metalwork fabrication to boilers and pressure vessels, light and medium stamping, shipbuilding and high-strength applications in the automotive sector.
Pickled steel is a form of steel that has undergone a pickling process. This operation entails the cleaning of the black material, by removing surface scale and oxide. The steel stripped of surface slag is then treated with corrosion inhibitors to preserve the surface appearance obtained.
This process allows the material to receive coatings such as:
