In recent years, the anti-corrosion lining titanium clad steel plate of the power plant has been widely used, which has the characteristics of high permeability and tightness, strong integrity, light self weight and high corrosion resistance. Titanium clad steel plate is a new composite material made of titanium plate and carbon steel plate by rolling technology. The cost of pure titanium is too high. So the titanium clad steel plate not only has the corrosion resistance of titanium plate and the mechanical properties of carbon steel plate, but also greatly reduces the costs.
