Titanium is widely used as material for various chemical reaction vessels and heat exchangers due to its excellent corrosion resistance, but its drawback is the high cost.Composite material made of titanium and ordinary steel is known as titanium-steel composite material, which combines the corrosion resistance of titanium with the structural strength of ordinary steel plate, significantly reducing the cost. With the rapid development of equipment manufacturing technology, the application fields of titanium clad steel plates will continue to expand.
The manufacture of petrochemical equipment containers is a traditional application field of titanium clad steel plates. In various acid, alkali, and salt media used in the chemical industry, except for four kinds of inorganic acids and highly corrosive aluminum chloride, titanium has excellent stability. Therefore, titanium is an excellent corrosion-resistant material in the chemical industry, and it is being increasingly widely used. For example, vacuum towers, distillation towers, heat exchangers in petroleum refineries, and various reaction towers, precipitation tanks, and agitators in chemical plants.
Titanium and its alloys have excellent resistance to seawater corrosion, chloride solution corrosion, and fluid erosion. The evaporator manufactured by titanium clad steel plates has good effects on slowing down corrosion and salt scaling, prolonging the production cycle, and improving salt quality. The application of titanium clad steel plates not only reduces the usage cost of salt plant equipment but also offers corrosion resistance superior to that of duplex stainless steel and has a longer service life, albeit at a lower market cost than using duplex stainless steel.
In the aerospace field, titanium clad steel plates have become indispensable materials due to their light weight, high strength, corrosion resistance, and high-temperature resistance. Titanium-steel composite plates are used to manufacture key components such as aircraft body structures, engine parts, and fuel tanks. Their high strength ensures structural stability, while their light weight reduces the aircraft's weight, enhancing flight efficiency. Additionally, the corrosion resistance of titanium clad steel plates ensures the long-term stable operation of aircraft in harsh environments.
In recent years, titanium clad steel plates have found new applications in marine civil engineering for corrosion protection of steel structures. The advantage of titanium clad steel plates is that titanium essentially does not corrode in seawater, and titanium metal ions will not leach out. Moreover, titanium is non-toxic to living organisms and has no impact on the surrounding ecological environment, making it an environmentally friendly material. Titanium-steel composite plates manufactured by continuous hot rolling are thin plates mainly used for lining marine steel structures, with applications in marine civil engineering.
In summary, titanium clad steel plates not only possess the excellent corrosion resistance of the titanium cladding but also offer the strength and plasticity of the carbon steel base layer, making them an ideal material choice for manufacturing equipment in corrosive environments. They are being promoted and applied in multiple fields, achieving significant economic benefits and contributing to the efficient use of rare and precious metal materials and the creation of a new green and environmentally friendly life.
