The stainless steel screw surface adheres to organic juices (such as melon, noodle soup, phlegm, etc.). In the case of water and oxygen, organic acids are formed, and the corrosion of organic acids to the surface of metals is long.
Although stainless steel screws have high comprehensive mechanical properties; But its corrosion resistance is not high; Therefore, it should be noted in the use of the situation: 1 can not contact with the rain directly; The situation of strong acid and alkali is not suitable; 3. The environment with large climatic humidity is not suitable; The seaside is not suitable; Chemical plants and other nearby are not suitable.
If it is to be used in the above situation; Must improve the corrosion resistance first; It can be treated on the surface by dacro or rustproof. Otherwise, you cannot use it directly.
In the process of storing stainless steel screw, it is necessary to strengthen the protection of the product, so that the environment can be dry, and the plating iron screws should not be put in the place of the tide. Also in the packaging process should be careful, can not be violent. If special requirements are not required, use mesh bags or other object packages to avoid touching each other.
