The stainless steel joint belongs to the metal product, it is a kind of connection head made of stainless steel plate, which also shows that it has the possibility of corrosion. So how should stainless steel joints prevent corrosion?
The surface corrosion resistance of stainless transition joints refers to the application of various methods to release a safety protective layer on the metal surface. Its effect is to protect the metal from the corrosive natural environment to manipulate the entire process of corrosion or reduce corrosive substances. Touch the metal surface to prevent or alleviate corrosion. The maintenance layer can meet the following requirements:
1. Corrosion resistance, wear resistance, high toughness.
2. The structure is tight, intact, and the gap is small.
3. It is separated from the base metal firmly and has good adhesion.
4. The average value is spread and has a certain thickness. The maintenance layer is generally divided into two categories: metal coating and non-metal coating. Metal coating refers to the use of a metal or aluminum alloy with strong corrosion resistance to form a maintenance layer on a very easily corroded metal surface. This type of coating is also called For coating. There are many methods and types of metal coatings. Among them, electroplating is the most common method, followed by molten metal immersion plating (hot-dip plating) and organic chemical surface treatment.
Non-metallic coating refers to the use of organic polymer raw materials such as paint and inorganic materials such as porcelain to form a maintenance layer on the surface of metal machinery and equipment or parts. This maintenance layer can protect basic metals and natural environmental substances in detail and prevent conventional metals. Corrosion occurs on stainless steel standard parts due to contact with corrosive substances.
