Why should oxalic acid be used in the production of stainless steel hexagon socket flat round head bolts?
The advantages of oxalic acid applied to the stainless steel hexagon socket flat head bolt wire are: one is to form a layer of lubricant on the surface of the wire to prevent direct contact between the wire surface and the mold, protecting the mold and extending the service life of the mold; the other is that the wire will become softer and easier to operate. However, there are also drawbacks to oxalic acid passing through stainless steel wires, which are that they cannot be stored for too long and are prone to oxidation. Therefore, during transportation, it is necessary to avoid packaging damage caused by collisions, resulting in oxalic acid being exposed to moisture and air.
However, not all bolts made of stainless steel wire require oxalic acid, and oxalic acid materials are generally used to produce bolts with large deformation.
The surface of stainless steel hexagon socket flat head bolts produced with oxalic acid can be difficult to clean, and they need to be treated by a specialized cleaning factory. Otherwise, when looking at the appearance of the finished product, the bolt may feel a bit dirty and not good-looking enough.
