How to prevent corrosion of stainless steel nuts? Do maintenance in advance

As a very important part, the raw material of stainless steel nut is metal material. Therefore, if it is stored improperly, there is a great possibility of corrosion damage. At present, there are four main methods for anti-corrosion of metal raw materials, namely metal raw materials. Its own characteristics, specific use of the local environment, the interface of raw materials and environmental contact, modify the design of the metal structure. If the nut is made of an alloy material that can completely resist corrosion, unless there are very special requirements, it is not very cost-effective. The second method is to completely isolate the surface of the nut from the environmental factors that may cause corrosion, but it is not possible in practice. OK, so it's tough.

Surface anti-corrosion treatment is the main method

Modifying the design of the metal structure can improve the environmental impact in a certain situation, but the structural design of most stainless steel nuts cannot be completely corrected, let alone self-maintenance, so this method is difficult to solve the basic problem, only in the The contact surface is anti-corrosion, so surface anti-corrosion treatment is the most widely used method at present.

Add maintenance layer

The anti-corrosion treatment on the surface of stainless steel nuts mainly refers to the use of various methods to add a maintenance layer to the metal surface. To avoid or reduce corrosion.

However, the maintenance layer needs to meet some requirements, it needs to be resistant to corrosion and wear, has high hardness, its own structure is tight and complete, the holes and gaps are relatively small, it is firmly separated from the base metal, and has good bonding characteristics. higher thickness.
