You can have your stainless steel constructions pickled and passivated at Raff + Grund. Machining and thermal processing as well as ferritic contaminations make stainless steel susceptible to corrosion. The pickling reliably removes these areas and therefore increases the durability and corrosion protection considerably. The passivating is carried out after the pickling and removal of the pickling residues, automatically in the air. The component then has the full corrosion resistance of the material and has the typical appearance of stainless steel. The components can also be additionally treated with special passivating in nitric acid. In this case the passive layer of the stainless steel in increased still further. This method can also be used for polished surfaces or materials that cannot be pickled.
