Utilization of stainless steel in sea water resources

Steel materials Since 1911-1912, the problem of preventing the rust of steel materials has been the subject of constant research by industry researchers. Stainless steel is a high-alloy steel material containing a variety of alloying elements. The industry mainly divides stainless steel into a variety of types such as austenitic system, ferritic system, martensitic system, biphasic system and precipitation hardening system.

With the lack of environmental resources for human survival, the use of sea water resources has become a top priority for humans to solve problems. Drinking water normally used and irrigation in agriculture require a large amount of fresh water resources. Transport from the mainland is not a desirable method, considering local conditions. Humans use fresh water to obtain fresh water and use fresh water resources.

 What constitutes the evaporator?
The evaporator is an important part of the low-temperature multi-effect distillation technology, and the casing is welded by a stainless steel plate (S32304) having a thickness of 8 mm. It is the most ideal equipment, but because of its high cost, it limits its application. In order to solve the problem of high cost, a new type of composite board was developed and studied. Use ordinary carbon steel and replace it with corrosion-resistant stainless steel.

      Choose the best composition material
The composite board is used as a top and side panel of a low-temperature multi-effect evaporator in a desalination facility, and the composite layer is on the inner side. There are a large number of microorganisms in the seawater, and the corrosion resistant stainless steel of the composite plate is to be operated under the environment of high salt, high temperature and sea water scouring.

Duplex stainless steel combines the corrosion resistance of both ferritic and austenitic stainless steels, and its structural properties are superior to those of a single body. The comparison of stress corrosion resistance of 22Cr duplex stainless steel, 304L and 316L steel in chloride solution shows that 22Cr duplex stainless steel has better stress corrosion resistance in chloride environment. Duplex stainless steel is the material of choice for refractory stainless steel.
   Compared with the existing grades of duplex stainless steel, choose a new type of duplex stainless steel with similar seawater corrosion resistant stainless steel formula.
