In concentrated sulfuric acid boiling reactors, desulfurization chimneys in high-humidity, corrosive environments, and deep-sea oil and gas platform equipment, a composite material consisting of a titanium and steel base layer is the ultimate solution for pressure vessels against extreme corrosion. It can withstand hundreds of atmospheres of pressure and corrosive media that even stainless steel finds difficult to resist, while costing only one-third as much as pure titanium equipment. It can withstand corrosive media and is only one-third the cost of pure titanium equipment. Performance Advantage: A low-cost solution to the problem of high corrosion.The core value of the titanium steel composite plate lies in its complementary materials:Titanium compound layer (TA1/TA2): Resistant to strong acids (such as concentrated sulfuric acid and acetic acid) and seawater corrosion. The annual corrosion rate is less than 0.001 mm, which is far better than stainless steel (such as 316L, which perforates in wet chlorine gas in only two years). The steel base (Q345R/16MnR) provides structural strength and a pressure-bearing capacity of more than 3.5 MPa at a cost of one-eighth that of titanium.The composite interface uses metallurgical bonding through explosion welding with a shear strength of more than 300 MPa to ensure zero media penetration. Application scenario: "Invisible Defender" on the battlefield of corrosion. 1. Chemical Equipment: Survival in a Strong Acidic Environment PTA (purified terephthalic acid) plant: A 1000 m² large-scale oxidation reactor condenser with a titanium composite layer that resists mixed corrosion from acetic acid and bromide at 180°C. 2. Electric power and environmental protection: Anti-corrosion revolution of the desulfurization chimney.Flue gas after wet desulfurization contains corrosive substances, such as SO₃ and Cl⁻. The titanium-steel composite plate chimney inner tube: It has a life span three times longer than an FRP coating solution and an overall cost that is 40% lower.3. New Energy and Marine Engineering LNG storage tanks have a titanium composite layer that resists the embrittlement and corrosion caused by -162°C liquid natural gas and hydrogen sulfide. The maintenance cycle has been extended from six months to five years. Desalination Equipment: The high-pressure pump shells are made of an exploded composite plate and are 50 times more resistant to chlorine-ion corrosion than stainless steel.

Titanium alloy plates have swept the material world with their light weight, high strength (density of 4.51 g/cm³ and strength up to twice that of steel), and extreme environmental adaptability (-253°C to 600°C stable operation and a seawater corrosion rate of less than 0.001 mm/year). More critical is its triple-core advantage: First, biocompatibility: the osteointegration rate of medical titanium plates exceeds 95%, and the Ti-6Al-7Nb alloy eliminates vanadium toxicity and reduces the wear rate by 60%. Performance adjustability: Alloying allows for precise matching of needs. For example, the resistance of a TA10 titanium plate to concentrated hydrochloric acid corrosion is 50 times greater than that of stainless steel. Process extensibility: It can be used for traditional rolling, explosion compositing, and 3D printing. It can be adapted for use with ultra-thin foils (0.089 mm) and wide, thick plates (3,300 mm). Titanium alloy application areas:1. Aerospace: Effectively enhances satellite load and is resistant to deep cold environments.2. Deep-Sea and Nuclear Energy: Withstands high-intensity water pressure and is highly corrosion-resistant.3. Medical and healthcare: The titanium alloy bone plate fits with high precision and has strong bending fatigue resistance and a short fusion cycle.4. Chemical ships: corrosion resistance, extended equipment maintenance cycles, and a service life far beyond that of other materials. Titanium alloy plate has become a “universal medium” for high-end manufacturing due to its plasticity and environmental adaptability, as evidenced by its use in everything from deep-submersible spherical shells to folding screen hinges.  

Explosive composite technology continues to push the limits of metal composites with its high-temperature, high-pressure operation and unlimited material possibilities. Titanium-steel composite products occupy a 30% market share in China, confirming their irreplaceability in high-end manufacturing. As the industry moves toward lightweight, corrosion-resistant, and functional upgrades, the explosive "aesthetics of violence" will continue to reveal new possibilities in the world of materials. The principle of technology: instant violence versus continuous pressure. Explosive composite:Through the detonation of explosives generated by high-speed impact (with a burst speed of 1,800–3,000 m/s), the "compound plate" is driven at high speed into the "substrate" in microseconds, achieving metallurgical bonding. Rolling composite:A hot rolling mill applies continuous pressure and a high temperature (1200-1250°C) to multi-layer stacked metal plates, bonding them through plastic deformation. A typical example is Anshan Steel's production of X65 grade nickel-based composite plates, which requires strict control of the rolling temperature, underpressure rate, and cooling rate. This process involves complex compositional corrections and modeling control. The three core advantages of Explosion Composite: 1. High degree of freedom in material combination Explosion composite can achieve the "marriage of metals" that traditional rolling finds difficult to reach: Titanium-steel: Used in nuclear power condensers and chlorine corrosion resistance. Life is 50 years (compared to 35 years for pure steel). Zirconium-steel/silver-steel: used in acetic acid towers and electronic-grade polysilicon reduction furnaces, breaking the foreign monopoly⁷. 3Cr13-Q355B is a high-wear-resistant composite realized by a transition layer of powder (carbonyl iron powder + cerium nitrate). It is used in centrifugal fans to resist particle wear.   2. Significant cost-effectiveness For example, the 601 + 310S heat-resistant steel plate is significantly more cost-effective. The price of imported 601 steel is eight times that of domestic 310S steel. The composite 601 dosage is reduced by 50%, which directly reduces the cost. The performance is close to that of pure 601 heat-resistant steel.   3. There is greater performance enhancement space. Explosion composite can be superimposed after vacuum quenching and other post-treatments, such as the 3Cr13-Q355B composite plate with 1000°C vacuum solid solution and water cooling. This process enhances the surface hardness by 40% and the shear strength by over 450 MPa. Due to the limitations of the high-temperature process, it is difficult to achieve such a high level of reinforcement through rolling composite.
