What is a metal clad plate?
Metal composite plate is a kind of plate which is covered with another kind of metal on a layer of metal. It has achieved the effect of saving resources and reducing costs without reducing the use effect (anti-corrosion performance, mechanical strength, etc.). There are usually explosive recombination, explosive rolling recombination, rolling recombination and so on. Composite materials can be divided into composite plates, composite pipes, composite rods and so on according to their appearance. Mainly used in anti-corrosion, pressure vessel manufacturing, electrical construction, petrochemical, pharmaceutical, light industry, automobile and other industries.
Metal composite plate is a composite material formed by metallurgical bonding of metals with different properties on the interface by various composite technologies. Through proper material selection and reasonable structure design, metal composite plate can greatly improve the thermal expansion, strength, toughness, wear resistance, corrosion resistance, electrical and magnetic properties of a single metal material.
Common metal composite plates are: titanium steel composite plate, copper steel composite plate, titanium-zinc composite plate, titanium-nickel composite plate, nickel steel composite plate, copper-aluminium composite plate, nickel-copper composite plate and so on.
Metal composite technology can give full play to the respective advantages of component materials, realize the optimal allocation of material resources of each component, save precious metal materials, and realize the performance requirements that a single metal can not meet. Taking stainless steel-steel composite plate for pressure vessel as an example, carbon steel (Q245R, Q345R, etc.) as the base has good mechanics. Yes, stainless steel (304, 316L, etc.) for cladding has good corrosion resistance. They are usually welded together by explosive welding. It only needs several millimeters of high-price stainless steel, which saves a lot of cost and hardly changes the mechanical properties of the substrate. It can not only replace imports and fill the domestic gap, but also has a wide range of applications, with good economic and social benefits, easy to get support and help from all aspects. For example, the development of stainless steel composite materials has been a high-tech project actively supported and advocated by the National Development and Reform Commission and the Ministry of Science and Technology.
