In 2011, stainless steel has just become the sought after, and all kinds of stainless steel standard parts bloom everywhere. Nowadays, stainless steel has been integrated into thousands of households!
The working principle of the stainless steel nut is self-locking by the friction between the stainless steel nut and the bolt. However, the reliability of this self-locking in dynamic loads is reduced. In some important cases, we will take some anti-loose measures to ensure the reliability of the locking of stainless steel nuts. Among them, the use of locking stainless steel nuts is one of the anti-loose measures.
In fact, people who know chemistry know that all metals react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel continues to oxidize, causing the rust to expand and eventually form pores. The carbon steel surface can be ensured by electroplating with paint or oxidation resistant metals (e.g., zinc, nickel, and chromium), but as is known, this protection is only a film. If the protective layer is destroyed, the underlying steel begins to rust. The corrosion resistance of stainless steel depends on chromium, but because chromium is one of the components of steel, the protection methods are different.
