Shaped parts often have cleaning problems after heat treatment, or because of improper operation, residual alkali on the surface will directly cause burns or corrosion on the surface. Shenzhen Shaped parts manufacturers will tell you below What should be paid attention to when cleaning?
   1.After the fasteners are quenched, they are cleaned with silicate and then rinsed. Some solid substances also appear on the surface. When the instrument is analyzed, it will be iron oxide or inorganic silicate. This is because the rinsing is not complete. Caused by the liquid above.
   2.During the use process, there will be some black item lines on it, and after rinsing after heat treatment, there will be black item lines after quenching. Analysis will find that higher concentrations of calcium and sulfur are used. It is due to the excessive aging of the oil used for quenching, it is recommended to use the old oil to replace with new oil.
   3.During tempering, there will be signs of discoloration. Soaking with ethanol will reveal oily residues left. This shows that the rinsing process was contaminated with quenching oil and cleaning agent. After heat treatment, It will leave scars, which is enough to show that the surface is not clean. This process is not due to quenching oil, but due to improper cleaning.
