Mulit layer clad plate

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.
