A processing method for improving corrosion resistance of stainless steel

Abstract

The invention belongs to the technical field of stainless steel plates and particularly relates to a machining method for improving corrosion resistance of stainless steel. The machining method comprises the steps of oil removal, cleaning for the first time, acid cleaning activation, cleaning for the second time, neutralizing treatment, cleaning for the third time, drying and packaging in a sealed mode. Compared with the prior art, the machining method has the following advantages that through the oil removal mode, the oil removal effect is good, operation is convenient and fast, and the machining time is shortened; a stainless steel substrate subjected to freezing treatment is activated after being passivated with an acid solution, the effect that the reaction is stable and complete can be ensured, and the corrosion resistance and antifouling performance of the stainless steel are improved; as cleaning is conducted with a cleaning solution, the operation method is simple, the surface decorativeness of stainless steel products can be improved, and pollution to the environment is low; and the stainless steel plates machined through the method are high in corrosion resistance, good in surface decorativeness and suitable for being popularized.

Description

technical field [0001] The invention belongs to the technical field of stainless steel plates, and in particular relates to a processing method for improving the corrosion resistance of stainless steel. Background technique [0002] Stainless steel has the characteristics of high hardness, good wear resistance, good corrosion resistance, excellent appearance and long life. It is widely used in construction, automobile industry, shipbuilding industry, marine equipment, mechanical equipment and chemical equipment and other industries. In the process of processing, pickling and passivation are usually required to improve the corrosion resistance of the product, but the current pickling and passivation process usually requires two steps to be carried out separately, and according to the existing pickling solution ratio, it will The stainless steel product after pickling and passivation is silvery white, which affects the decoration of the stainless steel surface, and its corrosi...
