The metal exterior wall composite panel has achieved the effect of saving resources and reducing costs without reducing the use effect (corrosion resistance, mechanical strength, etc.). Composite methods usually have explosive composites, explosive rolling composites and rolling composites. Mainly used in anti-corrosion, pressure vessel manufacturing, power construction, petrochemical, pharmaceutical, light industry and automotive industries.
Metal composite technology can give full play to the advantages of component materials, realize the optimal configuration of raw materials of each group, save precious metal materials, and achieve performance requirements that cannot be met by single metal. Stainless steel and steel composite plates for pressure vessels For example, the base layer has good mechanical properties with general carbon steel (Q245R, Q345R, etc.), and the double layer stainless steel (304, 316L, etc.) has good corrosion resistance. The two are usually combined with explosion welding. High-priced stainless steel of a few millimeters saves a lot of cost and hardly changes the mechanical properties of the substrate. It can replace imported and fill domestic gaps, and has a wide range of applications, with good economic and social benefits, and easy to obtain support and help from all aspects.
