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.
