Pickling surface treatment
Webb27 dec. 2024 · In order to obtain such a surface, the hot rolled strip needs to be treated to remove iron oxide from the surface, usually by pickling. There are generally two types of iron oxide on steel pipes : one is the oxide – rust – generated at room temperature, in a humid environment, and with SO2, CO2 dissolved in moisture to act as a catalyst. WebbInstead, the surface of the stainless steel is treated with an oxidizing acid, to dissolve carbon steel, sulfide inclusions and remove iron and other surface contaminants from the stainless. The acid further works to promote the formation of the chromium-rich passive film, which imparts the corrosion resistance quality.
