Titanium is widely used as a material for various chemical reaction vessels and heat exchangers due to its excellent corrosion resistance, but its disadvantage is its high cost. The composite material made of titanium and ordinary steel is called titanium steel composite material, which combines the corrosion resistance of titanium and the structural strength of ordinary steel plate, greatly reducing the cost. With the rapid development of equipment manufacturing technology, the application field of titanium composite steel plate will continue to expand.

 

Petrochemical and chemical container equipment manufacturing

 

Petrochemical equipment container manufacturing is the traditional application field of titanium composite steel plate. Among the various acid, alkali and salt media used in the chemical industry, titanium has excellent stability except for four inorganic acids and highly corrosive aluminum chloride. Therefore, titanium is an excellent corrosion-resistant material in the chemical industry and is increasingly widely used. For example, vacuum towers, distillation towers, heat exchangers in oil refineries, various reaction towers, sedimentation tanks, agitators in chemical plants, etc.

Vacuum salt making equipment manufacturing

 

Titanium and titanium alloys have excellent resistance to seawater corrosion, chloride solution corrosion, and fluid erosion. The use of titanium composite steel plates to manufacture evaporators has significant advantages in slowing down corrosion, delaying salt scale formation, extending production cycles, and improving salt product quality. The use of titanium composite steel plates not only reduces the use cost of salt plant equipment, but also has better corrosion resistance and longer service life than duplex stainless steel, but the market cost is lower than duplex stainless steel.

 

Aerospace field

 

In the aerospace field, titanium composite steel plates have become an indispensable material 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 components, and fuel tanks. Their high strength ensures the stability of the structure; their light weight reduces the weight of the aircraft and improves flight efficiency; in addition, the corrosion resistance of titanium composite steel plates ensures the long-term stable operation of aircraft in harsh environments.

 

Marine engineering

 

In recent years, titanium composite steel plates have found new applications in marine civil engineering for the anti-corrosion of steel structures. The advantage of titanium composite steel plate is that titanium is basically not corroded in seawater, and titanium metal ions will not precipitate. Moreover, titanium is non-toxic to organisms and has no effect on the surrounding ecological environment. It is an environmentally friendly material. Titanium steel composite plate produced by continuous hot rolling is a thin plate mainly used for the lining of marine steel structures and is also used in marine civil engineering.

 

In summary, titanium composite steel plate has both the excellent corrosion resistance of the titanium composite layer and the strength and plasticity of the carbon steel base layer. It is an ideal material for manufacturing equipment in corrosive environments. It has been promoted and applied in many fields and has achieved significant economic benefits. It has contributed to the efficient utilization of rare and precious metal materials and the creation of a green and environmentally friendly new life.
