Improve the competitiveness of stainless steel shaped tubes, the need to improve today, the whole development of stainless steel shaped tubes industry has shown a state of imbalance in the current stainless steel Pipes industry soared situation, the source of raw materials is very tight domestic supply serious shortage, basically mainly rely on imports to sustain the development of the original. In the case of iron ore rose also increased the cost of stainless steel, Baosteel stainless steel wholesale jewelry line for today's fierce market competition, stainless steel jewelry line professional services, it is difficult to compete, to create difficulties in production and operation of enterprises. Pipes for surface roughness using stainless steel pickling method for processing generally refers to a method for cleaning a metal surface. Usually the workpiece is immersed in an aqueous solution of sulfuric acid to remove the oxide film such as a metal surface. Plating, enamel, rolling and other processes of pre-treatment or intermediate treatment, Which is good quality stainless steel jewelry wire, concrete steps are as follows: (a) with an acid solution process scale and corrosion products on the steel surface to remove called acid wash. Scale, rust and other iron oxide (Fe3O4, Fe2O3, FeO, etc.) with an acid solution of a chemical reaction to form a salt dissolved in the acid solution is removed. Pickling acids are sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, chromic acid, hydrofluoric acid and a mixed acid. The most commonly used are sulfuric acid and hydrochloric acid. Pickling process are dipping pickling, spray pickling rust and acid paste method. More generally pickling by dipping, spraying method can be used in mass production. Pipes in stainless steel parts are generally 10% to 20% (by volume) sulfuric acid solution at a temperature of 40 ℃. When the solution of the iron content of more than 80g / L, ferrous sulfate than 215g / L, should replace the acid lotion. At room temperature, stainless steel jewelry line, a solution of hydrochloric acid with 20% to 80% (by volume) of steel pickling, corrosion and hydrogen embrittlement easily happened. Since the acid corrosion of metals on the great need to add corrosion inhibitors. After cleaning the surface of a silver-white metal, while the passive surface and improve the corrosion resistance of stainless steel Pipes.
