One is carbon steel, which is the most commonly used material for ordinary centrifugal fans. It refers to iron-carbon alloy steel with carbon content less than 2.11%. This material is easy to process and cheap, and is suitable for most centrifugal fans with normal temperature and no dust and corrosion.
Another main material is FRP, also known as FRP, which is commonly used for anti-corrosion centrifugal fans. This material has excellent anti-corrosion properties, corrosion resistance to various acids, alkalis and salts, and a considerable number of gas treatment in the chemical industry will be used in FRP centrifugal fans.
Stainless steel is also a common main material for centrifugal fans, but it is not only a material, but also a category containing more than 100 specific materials, including martensite, austenite, ferrite, dual-phase stainless steel and other categories. Stainless steel is a common main material for anti-corrosion centrifugal fans and high temperature centrifugal fans. It can resist both corrosion and high temperature. Of course, the price is much higher than the above two.
In addition, there are centrifugal fans will choose plastic as its main material, generally PP. But because its strength is lower than that of FRP, it has a smaller scope of use and is rarely large, but its special characteristics may be used in anti-corrosion fans.
In addition, there are centrifugal fans made of titanium alloy, steel-lined plastic, steel-lined fiberglass reinforced plastics and other special materials and composite materials. Although rare, they will also play an important role in specific fields. Users should be determined by professionals according to specific working conditions.
