special stainless screw will corrode and rust

Many people think that special stainless screw are screws that will not rust, but in fact stainless steel non-standard screws do not necessarily rust, but relatively speaking, stainless steel non-standard screws are more resistant to corrosion and rust than iron screws. However, special stainless screw will still rust under certain conditions. So what is the reason for the stainless steelspecial screw rust? What conditions lead to rust?

Special stainless screw have good characteristics, high temperature resistance, strong corrosion resistance and certain rust resistance. However, in the harsh environment, it will still rust. Like in a very humid environment, the wind is blowing in the sun, and the rain is blowing. After a long time, it will definitely be a little rusty. Or contact with some acid-base chemicals to produce a chemical reaction that causes corrosion and rust. There are also special screw for stainless steel materials that are not suitable for use in a specific occasion. The material is stainless steel SUS201 non standard screws. It is not suitable for use at sea. Because seawater is salty, it is used at sea for a long time. Soaking in sea water can cause corrosion and rust. Therefore, stainless steel SUS316 is generally not recommended for use in marine products.

It is not difficult to conclude from the above that special stainless screw will corrode and rust under certain conditions. This requires us to use stainless steel non-standard screws, it should be used reasonably, under different conditions, use stainless steel non-standard screws of different materials. In different occasions, when using stainless steel non-standard screws, pay special attention to the details, and try to control the corrosion and rust of stainless steel non-standard screws.
