Stainless steel double headed stud is a kind of stainless steel screws, according to the material, use, level of different, its technical parameters and specifications are also different. Stainless steel double headed stud are called stainless steel double-headed screw because they are produced with stainless steel SUS304, SUS316 and other raw materials. So how to prevent rusting of stainless steel double headed stud? Aozhan fasteners to give you the answer.
Stainless steel double headed studs are widely used in equipment manufacturing, construction and other fields. The manufacture, transportation and installation of stainless steel double headed studs are required to comply with the national industry standards for double headed studs. Common double headed studs national standards GB897, GB898, GB899, GB900, GB901 these five kinds. According to the use of different industry sectors, there are many national standards, such as HG20613, HG20634 and other specifications. Double headed studs are mainly used for the linked parts are too thick to use screws or because of frequent disassembly and installation should not be used for screw links, double headed studs are usually screwed into the screw hole at one end, the other end is connected with a nut.
Stainless steel double headed stud are commonly used as standard fasteners. Double headed stud in the use of a long time, by the external environment, rust is a common thing. Double headed stud rust will not only directly affect the level of beauty and generosity, but also directly affect its performance. Therefore, when we apply stainless steel double headed stud, we must understand the causes of rust, and timely measures to effectively avoid.
What are the causes of rusting of stainless steel double headed studs?
1. Stainless steel double headed studs surface adhesion with acid, alkali, acid salts and other chemicals (such as indoor decoration wall edible alkali, lime water splash), resulting in partial corrosion.
2. In the air with damage (such as with a lot of sulfate, carbon dioxide, sulfur oxide air ), condensate, hydrochloric acid, sodium cyanide, glacial acetic acid liquid point, resulting in chemical corrosion.
3. Soot or metal material particulate appendages, in the wet and cold air, appendages and stainless steel screws condensation, the two will be connected into a micro-chargeable battery, caused by electrochemical corrosion, protective film damage, known as electrochemical reaction.
4. Stainless steel screw surface adhesion of organic compounds liquid (such as vegetables, soup noodles, spit, etc.), in the presence of oxygen, composed of organic matter, long-term organic matter on the surface of the metal material leaching corrosion.
Stainless steel double headed stud rust problem solution：
1.First use stainless steel cleaning agent on the surface for oil removal, rust removal, after three minutes of treatment screw bright as new, can restore the original luster of the screw, does not hurt the screw substrate, and has a short anti-rust performance.
2. Stainless steel double headed stud rust prevention can be used stainless steel passivation solution. Only need to use the plastic tank at room temperature, passivation time of 1 hour, passivation does not change the size and appearance of the screw, while the surface to form a passivation film, can prevent the screw from rusting again, passivation screw bright, clean surface, while extending the service life of stainless steel screws.
