What are the surface treatment processes for stainless steel bolts in Shanghai Yaluo?
This time, Shanghai Yaluo Precision Fastener Technology Co., Ltd. will tell you about the metal surface treatment of stainless steel bolts in Shanghai. Under normal circumstances, Shanghai stainless steel bolts do not require any treatment. Only when requested by customers, will some metal surface treatment processes be carried out. Let's take a detailed look below. The main contents are as follows:
1. Electroplating: Dip the parts to be electroplated into a solution containing accumulated metal oxides, and use the amount of current according to the plating solution to cause the electroplated metal to precipitate and adhere to the parts. Usually, electroplating includes hot-dip galvanizing, copper, nickel, chromium, nickel alloys, etc.
2. Hot dip galvanizing: It is completed by immersing carbon steel components in a zinc plating bath with a temperature of approximately 510 ℃. The result is that the iron zinc alloy on the surface of the steel gradually becomes passive zinc on the outer surface of the product. Hot dip aluminum plating is a similar process.
3. Mechanical plating: impact the surface of the product based on the particles of the coated metal, and cold weld the coating onto the surface of the product. Usually, bolts are mostly electroplated, but they are used in outdoor hexagonal wood screws such as electric power and highways, and hot-dip galvanized; The cost of electroplating is usually 0.6-0.8 yuan per kilogram, while hot-dip galvanizing is generally 1.5-2 yuan per kilogram, which is relatively high.
Based on the relevant content in the article, I believe everyone should have a certain understanding of the metal surface treatment of Shanghai stainless steel bolts.
