Stainless steel bar is a kind of steel with good adaptability to the environment, strong acid and alkali resistance and corrosion resistance. Because it has the characteristics of being not easily rusted, it plays an incomparable role in many industries, including some. In the special environment, the stainless steel bar is a kind of stainless steel, and it is a very common one. It has various series, the most common ones are two series, three series, four series, etc. Different ingredients make them perform more powerfully in certain qualities. Stainless steel bars are not available for use. There is a process before use. This process is pickling. Only the acid-washed stainless steel bars are more durable.
The stainless steel bar looks very strong. In fact, it changes in the air. The oxidation of the air will make it covered with a black film. Don’t think that this film can protect the steel. The scientific name of this film is called oxide film. If this film is not treated, it will affect the performance of stainless steel and shorten its life. Therefore, it is only possible to remove this layer before pickling and pickling. It has more powerful corrosion resistance, and pickling is an important process to strengthen the function of stainless steel bars.
In addition to removing an oxide film on the surface of the steel, pickling should also remove impurities and garbage from the surface. Because the steel is exposed to the air, dust or other substances will adhere to the surface of the steel. If it is not treated, it will not only affect the visual effect, but also will easily rust in the future, and it will be acid-white after pickling, which not only makes the surface look better, but also greatly improves its performance and lays good for future use. basis.
Before pickling, do some preparatory work. There are also some precautions. First, wipe off the dust and other debris on the surface. If there is rust on the surface, you must first clean the rusted area. You must know that the acid washing is not good. It will protect the steel and destroy some of its properties. Pickling is a scientific way to form a more compact oxide film on the surface. Although this oxide film is very thin, it can prevent it. The steel body reacts with the external bad gas or even the chemical substance to strengthen the oxidation resistance and corrosion resistance of the stainless steel bar and adapt to various harsh conditions.
The first job of stainless steel bars before pickling is to remove debris. In addition to garbage and dust, there are also burrs on the surface of the steel during processing and garbage on the surface. Because these things have strong adhesion, just wipe Can not be completely cleaned up, this time can be cleaned with organic solution, or rubbed with gasoline, cleaned stainless steel bar should be aired, dried before it can be officially pickled.
