Large deformation resistance of stainless steel wire, when drawing easily stick to the mold Hongmei stainless steel wire shops, causing surface scratches. In order to ensure the smooth progress of the drawing, the wire must be appropriate surface treatment. Surface treatment including removal of surface oxide and the two elements attached to the surface coated with a good lubricating coating. More alloying elements of stainless steel wire, a complex oxide surface. It is necessary to first introduce the common nature of stainless steel wire element and its oxides: chromium and its oxides: chromium in the base, nitric acid, and organic acids carbonate solution is very stable, but soluble in concentrated hydrochloric acid and heat sulfuric acid. It generates three chrome oxide: CrO, Cr2O3, CrO3, CrO very unstable, oxidation of Cr2O3 in the air. Cr2O3 is a green insoluble substance, practically insoluble in acid solution. CrO3 is chromic anhydride, can be dissolved in sulfuric acid and nitric acid solution. Pretreatment before pickling stainless steel wire Stainless steel wire rod after rolling Hou Hongmei stainless steel wire manufacturer, scale and collective stainless steel wire with a solid surface, difficult to remove, if Hongmei directly pickling stainless steel wire market price, the effect is not very good, So you can start with a pre-treatment measures, and the use of an oxidant, activator mixed acid cleaning can be more effective removal of stainless steel oxide. Stainless steel wire commonly used pretreatment method in two ways: alkali leaching and blasting.
