The material of the spiral vane and the advantages of the carbon steel spiral vane

Screw conveyors are widely used and are often used for conveying materials, such as massive, granular, powdery and other materials, or some high-temperature and corrosive materials, instead of manual handling and higher efficiency. Common spiral blades include ordinary carbon steel blades, high manganese steel blades and stainless steel spiral vane.

The methods for manufacturing blades of screw conveyors in China include: single-piece stamping and welding forming, extrusion forming, winding forming, cold rolling forming and other methods. Screw conveyor blades can be divided into ordinary carbon steel blades, stainless steel blades, and manganese steel blades according to their materials.

The advantages of ordinary carbon steel blades can be higher hardness and better wear resistance after heat treatment, the hardness in the annealed state is very moderate, there is better machinability, the production cost is low, and the price is cheap.
