How To Avoid Wrong Tips When Using China Fasteners

      China fasteners are mechanical objects used to fasten various objects from toys to submarines. These China fasteners are made of high-grade materials such as stainless steel, alloy steel, steel, brass, aluminum, and plastic. China fasteners can be surface-finished to improve corrosion resistance and/or appearance. This article focuses on common mistakes to avoid when using China fasteners.

　　The following are some negative factors that need to be paid attention to when using China fasteners:

　　Choosing the incorrect type or grade: One of the key prerequisites is to choose the correct grade and type of material to be used. Depending on your application, you must choose between stainless steel, steel, alloy steel, brass, aluminum, or plastic. The stainless steel 300 series has the most corrosion resistance. Steel is cost-effective, brass is best for welding or brazing, aluminum is light, and plastic is suitable for marine applications.

　　Do not choose the correct surface treatment: Surface treatment is an effective way to obtain better corrosion resistance. Most China fasteners, such as hinges, downpipes, and accessories, become rougher or form cavities over time. This traps tiny particles in it, causing rust or staining and distorting the appearance.

　　Incorrect cleaning schedule: The service life of China fasteners depends on the regular cleaning schedule. If contaminants are allowed to accumulate for a long time, the cleaning process becomes difficult, which may also distort the appearance of the material. In addition, if the surface is exposed to rain, the dust particles will be washed away and the protective layer of China fasteners will also be removed.

　　Adapt to low nickel stainless steel: Compared with corrosion-resistant stainless steel, most of the 200 series stainless steel China fasteners lack chromium content and are more prone to rust. Therefore, it is recommended not to choose low-nickel stainless steel.

　　Make conditions favorable for galvanic corrosion: Galvanic corrosion is an electrochemical process in which two different metals corrode each other when they are in electrical contact. It will not only affect the stainless steel China fasteners but also damage the metal in contact with China fasteners. Nylon washers help prevent them from touching.

　　Exposure of contaminated surfaces: When stainless steel China fasteners are exposed to the atmosphere that is already easily polluted by metal dust or corrosive particles, it will accelerate the rusting process. This will also cause physical attenuation of the material. An iron filler can be placed inside the material to fill the rusty cavity. Therefore, stainless steel China fasteners must be used to cover the affected area during this process.
