Product Introduction
Zirconium titanium steel three layer transition composite plate is an extreme heavy-duty anti-corrosion multi-metal composite material prepared using a high-energy explosive cold welding process. It employs an innovative transition layer structure design: industrial pure zirconium as the anti-corrosion coating, pure titanium as the intermediate transition buffer layer, and carbon steel as the structural load-bearing base layer, achieving complete metallurgical bonding between the three layers. Unlike traditional two-layer zirconium-steel composite plates, the titanium transition layer effectively avoids the industry pain point of brittle intermetallic compounds easily forming at the interface when zirconium and steel are directly composited, improving interface toughness by over 60% and significantly enhancing resistance to cracking during deep processing. The product simultaneously combines the superior acid corrosion resistance of zirconium, the excellent dissimilar metal transition compatibility of titanium, and the high structural load-bearing capacity of steel. It can withstand extreme high-temperature, high-pressure, and strong acid conditions that titanium, stainless steel, and ordinary two-layer composite plates cannot handle, and is widely used in high-end fields such as chemical high-pressure reactors, hydrometallurgical high-pressure leaching tanks, and nuclear power plant corrosion treatment equipment.

Product Features and Applications
Product Advantages
The titanium transition layer fundamentally solves the problem of easy formation of brittle intermetallic compounds when zirconium-steel is directly composited. It significantly improves the interface toughness and bending/stamping resistance, and significantly reduces the risk of deep processing cracking. It is the preferred solution for high pressure and alternating load conditions.
Explosion-driven sequential atomic-level metallurgical bonding of zirconium-titanium and titanium-steel dual interfaces is achieved. The bonding strength far exceeds that of rolling and brazing composites. After rolling, spinning, and welding, there is no delamination, which fully meets the pressure-bearing design requirements of pressure vessels.
Zirconium layers exhibit excellent resistance to most strong corrosive media, such as high-temperature concentrated hydrochloric acid, phosphoric acid, acetic acid, and mixed acids. Their resistance to pitting and crevice corrosion is far superior to that of titanium and stainless steel, making them suitable for most extreme heavy-duty corrosion protection conditions.
Through the structural design of titanium transition layer + steel base layer, the material cost is reduced by more than 70% while achieving the same anti-corrosion effect as pure zirconium equipment, and at the same time the structural strength and equipment safety are greatly improved.
It can perform deep processing such as rolling, head spinning, stamping, CNC machining, and welding, and is equipped with a dedicated three-layer welding process solution to support the production of various high-pressure corrosion-resistant equipment components.
Application Areas
Petrochemical industry: high-temperature and high-pressure strong acid reactors, heat exchangers, high-pressure towers, and linings for hydrochloric acid/phosphoric acid production equipment.

Professional Consultation Q&A
Q1: Why is a titanium transition layer added between zirconium and steel? How does it differ from a double-layer zirconium-steel composite plate?
A1: Direct explosive welding of zirconium and steel can result in the formation of brittle intermetallic compounds at the interface, leading to reduced interfacial toughness and increased susceptibility to cracking under bending, stamping, and long-term alternating loads. A titanium transition layer effectively isolates zirconium from steel, preventing the formation of brittle phases and increasing interfacial toughness by over 60%. Three-layer composite plates offer superior processing performance and a higher safety factor, making them an ideal choice for high-pressure vessels and equipment subjected to long-term heavy loads.
Q2: What are the key points for welding this type of three-layer composite plate?
A2: The welding process employs a layered, step-by-step approach: first, a steel base layer is welded using carbon steel welding consumables; then, a titanium transition layer is welded using titanium-based filler material to prevent dilution by iron; finally, a zirconium cladding layer is welded using pure zirconium matching welding consumables. Strict heat input control is essential during welding, with inert gas protection applied to both the front and back of the weld, and mixing of different metals must be avoided. We can provide a complete Welding Procedure Specification (WPS) and a full set of matching welding consumable recommendations for each project.
Q3: In which extreme working conditions is this three-layer composite board suitable for applications where ordinary composite boards cannot be adapted?
A3: Primarily suitable for rapid failure conditions of titanium, stainless steel, and two-layer composite plates: high-temperature concentrated hydrochloric acid above 150℃, high-pressure mixed acid of hydrochloric acid and sulfuric acid, high-temperature phosphoric acid containing fluoride ions, and high-pressure alternating load corrosion environments. Widely used in pressurized oxidation leaching of hydrometallurgical and fine chemical high-pressure reactors.
Q4: How to ensure the reliability of the connection between the two mating surfaces? Will delamination failure occur during long-term use?
A4: We conduct 100% ultrasonic (UT) flaw detection on each zirconium-titanium and titanium-steel interface, and perform shear strength sampling tests on each batch of products to ensure that both interfaces meet the standard requirements. This metallurgical interface is free of pores and gaps, and will not form channels for media penetration; as long as it is processed and used according to specifications, it will not experience delamination failure during long-term service.
