Product Introduction
Titanium steel explosion composite plates are bimetallic metallurgical composite plates manufactured using a high-energy explosion cold welding process. The entire production process adheres to the ASTM B898 composite metal plate standard and the ASME SB-898 composite plate standard for pressure equipment . The titanium cladding and steel base layer achieve a complete metallurgical bond without brittle intermetallic compounds, with interfacial bonding strength far exceeding international standard requirements. The product combines the excellent acid and alkali resistance, chloride ion resistance, and pitting corrosion resistance of the titanium layer with the high strength, ease of welding, and cost-effectiveness of the carbon steel/stainless steel base layer. Only a thin titanium layer is needed on the surface in contact with corrosive media to achieve long-term corrosion protection. Compared to pure titanium plates, this reduces material costs by 50%-70%, solving the industry problem of easy cracking and poor bonding when directly welding dissimilar metals like titanium and steel. It is widely used in pressure vessels, reactors, flue gas desulfurization, marine corrosion protection, nuclear power, and other heavy-duty corrosion-resistant applications, making it a core structural material for cost reduction and efficiency improvement in the chemical, energy, and marine industries.

Product Features and Applications
Product Advantages
Explosion-driven high-speed collision achieves atomic-level metallurgical bonding, with a uniform wave-shaped interface. The shear strength far exceeds that of rolled composite plates. It does not delaminate after bending, stamping, rolling, and welding, meeting the pressure-bearing requirements of pressure vessels.
The titanium layer resists corrosion from strong acids, chloride ions, seawater, and other media, while the steel base provides structural strength and weldability, thus balancing corrosion resistance and structural mechanical properties.
Only the corrosion contact surface uses precious metal titanium, while the main body uses low-cost steel. Compared with pure titanium plates, it saves 50%-70% of material costs under the same corrosion protection life, which greatly reduces the overall cost of the equipment.
It can perform deep processing such as rolling, stamping, CNC machining, welding, and head spinning, and supports the production of pressure vessel components such as cylinders, heads, tube sheets, and flanges.
Under chemical corrosion conditions, its service life is 5-10 times that of stainless steel equipment. The titanium passivation film can self-repair, and there is no risk of corrosion and leakage during long-term operation, resulting in extremely low maintenance costs.
Application Areas
Petrochemical Industry: pressure vessels, reactors, heat exchangers, towers, and pipe linings.
Chlor-Alkali Salt Production: electrolytic cells, evaporators, brine conveying equipment, and salt slurry reaction equipment.
Environmental Engineering: flue gas desulfurization and denitrification spray layer, desulfurization tower lining, and sewage treatment anti-corrosion components.
Marine Engineering: seawater desalination equipment, subsea pipelines, and corrosion-resistant structural components for offshore platforms.
Nuclear Power Metallurgy: components of nuclear power cooling systems, hydrometallurgical leaching tanks, and electrolytic cell shells.
Light Industry And Pharmaceuticals: pharmaceutical reaction equipment, food-grade anti-corrosion containers, and vacuum salt production equipment.

Professional Consultation Q&A
Q1: What international standards does your company's titanium-steel composite explosion-proof plate meet?
A1: Our products strictly adhere to ASTM B898 (Standard Specification for Reactive Refractory Metal Composites) and ASME SB-898 (Pressure Vessel Class) standards. The titanium layer conforms to ASTM B265, and the steel substrate conforms to ASTM A516/ASTM A240. Each batch of products comes with an EN 10204 3.1 factory inspection report.
Q2: What are the differences between explosive welding and rolled titanium steel plates?
A2: Explosive welding can form a complete metallurgical bond with a shear strength ≥ 200 MPa . There is no delamination after bending, rolling, and welding, making it suitable for pressure vessels and heavily corrosive environments. Rolled welding only achieves a mechanical bond with lower strength and is easily peeled off during deep processing, making it only suitable for simple planar lining applications.
Q3: Which type of base steel should be selected for pressure vessel equipment?
A3: SA-516 Gr.70 carbon steel is the most commonly used base steel for pressure vessels, possessing excellent weldability and high-temperature toughness. If the base material requires weaker corrosion resistance, 316L stainless steel can be selected.
Q4: What is the minimum thickness of the titanium cladding layer to ensure long-term corrosion resistance?
A4: For general chemical corrosion and seawater environments, a 2mm thick Gr2 titanium cladding layer can guarantee a service life of more than 10 years; for harsh environments such as strong acids and high temperatures, we recommend using a 3-4mm thick Gr7 or Gr12 titanium alloy cladding layer.
