Description

technical field [0001] The invention relates to a stainless steel chemical polishing liquid, in particular to a stainless steel chemical polishing liquid which does not contain nitric acid and does not generate nitrogen oxide harmful gas during the polishing process. Background technique [0002] With the progress of society and the development of science and technology, stainless steel metal products are more and more widely used in various fields of industry, agriculture and people's life, and at the same time, they have created more and more value for society. Generally, the surface roughness of stainless steel products is extremely high, and sufficient polishing treatment is required. [0003] At present, the methods of polishing stainless steel in the metal processing industry mainly include mechanical polishing, chemical polishing and electrochemical polishing. Among these methods, mechanical polishing has a high cost in terms of high-temperature pickling and mechanic...
