Many people think that stainless steel non-standard screws will not rust. In fact, this is a wrong understanding. Although stainless steel non-standard screws are less prone to rust than iron screws, it does not mean that they will not rust at all. In other words, they have good anti-rust ability and are not easy to rust under certain conditions.

Generally speaking, non-standard stainless steel screws have good characteristics, corrosion resistance, high temperature resistance, and rust resistance. However, if they are stored and used in a humid environment for a long time, rust on the surface of the screw is inevitable.



In addition, if stainless steel non-standard screws and some acid-base chemicals are stacked together, a chemical reaction may occur, causing the screws to rust

There are some occasions where stainless steel non-standard screws are not suitable for use, such as in the sea, because the sea water itself contains salt, these screws will rust and corrode if they are immersed in sea water for a long time.

It can be seen from the above that in some environments, stainless steel non-standard screws will rust, so when using this type of screw, pay attention to the environment and use it reasonably.
