What is a titanium steel composite plate?
Titanium steel composite plate is a material manufactured from titanium and steel plates, typically produced through explosive bonding or hot rolling. Explosive bonding uses high-pressure shock waves to link metals, while hot rolling achieves strong bonding by rolling at high temperatures.
Titanium is frequently utilized as a material for various chemical reaction vessels and heat exchangers due to its exceptional corrosion resistance; nonetheless, it is expensive. This problem is most noticeable when employed as a structural component. Using titanium steel clad plates is an excellent solution. Titanium steel composite material is a material that combines the corrosion resistance of titanium with the structural strength of regular steel plates. More importantly, the cost is significantly decreased.

Advantages of Titanium Steel Composite Tube Sheet
Good corrosion resistance
Titanium has a high affinity for oxygen and can create a dense oxide film on its surface, which protects it from mild corrosion. Metallic titanium can generate a passivation oxide coating on its surface in most aqueous solutions. As a result, titanium is stable in acidic, alkaline, neutral salt solutions, and oxidizing media, and it resists corrosion better than stainless steel and other regularly used nonferrous metals.
The titanium layer has significantly higher corrosion resistance in chloride ion and acidic conditions than 304/316L stainless steel.
Reduce expenses
The titanium layer that meets the medium is 3-12mm thick, while the steel matrix is made from low-cost materials. The total cost is 35-50% less than that of pure titanium plates.
Lightweight
The density of titanium is less than that of steel. As a result, at the same size, the titanium-steel composite plate weighs significantly less than the pure steel plate, reducing the overall weight of the heat exchanger and the strain on the supporting structure. Its ideal for offshore platforms, transportable equipment, and other scenarios.
Good stability at high temperatures and pressure.
Use of Titanium Clad Steel Tube Sheet
Titanium steel composite plates are used in a variety of industries, including petrochemicals, electricity, salt production, and metallurgy. In recent years, titanium steel composite plates have also become popular in wastewater treatment and maritime engineering.
1. Petrochemical Industry
In the realm of petrochemicals, titanium, as an outstanding corrosion-resistant material, has exceptional stability in acid, alkali, and salt solutions. As a result, titanium/steel composite plates are commonly employed in equipment such as concentration towers, reactors, heat exchangers, pressure surge tanks, reactors, and condensers.
Titanium/steel composite tube sheets are the most commonly used materials in shell and tube heat exchangers.

2. Power-generating equipment
Titanium/steel composite plates are also extensively used in power plant condensers, condensers, and heat exchangers in saltwater desalination plants.
3. Salt-making equipment
Titanium offers great resistance to seawater and chloride solution corrosion, as well as fluid scouring, making it ideal for use as the shell material of salt evaporators. This successfully prevents salt scale from building on the evaporator wall, extending the tank washing cycle.
4. Metalwork
Titanium/steel composite plates are commonly utilized in metallurgical engineering to create horizontal or vertical reactors for wet pressure acid leaching of resources such as cobalt-nickel sulfide concentrates, laterite nickel ore, and rare precious metal slag.
