Stainless steel screws are small, but they have a huge effect. The use of stainless steel screws requires regular maintenance to ensure safer use of stainless steel screws, and can extend the service life of stainless steel screws and improve the performance of mechanical equipment.
When we are doing maintenance on stainless steel screws, there are three main problems:
1. When the stainless steel screws are quenched, the silicate cleaning agent should be used to clean the impurities. Then carefully rinse them to avoid the impurities remaining on the stainless steel screws, which affects its normal application.
2. After the stainless steel screw is tempered, its color may change. After the stainless steel screw is soaked in the ether for a period of time, oily substance will be produced. This situation indicates that the stainless steel screw is not clean enough. After the analysis, it will be found that the stacking of the stainless steel screws is not very reasonable, stainless steel screws may have some small oxidation in the quenching oil.
3. If there is a white substance on the stainless steel screw, it is probably some phosphide. The reason for this phenomenon is that there is no cleaning with an acid cleaner, and it is not careful enough to check the rinsing tank.
