Recently, Baotai Composite Materials Company, a subsidiary of Baotai Group, has made important breakthroughs in the explosive bonding technology for titanium‑steel clad plates. It has successfully overcome the manufacturing challenges of ultra‑thick cladding titanium‑steel clad plates for autoclaves and large‑area titanium‑steel clad plates for PTA chemical equipment, advancing the localization of high‑end titanium‑steel clad plates to a new level.
Titanium‑steel explosive clad plates combine the excellent corrosion resistance of titanium and the high strength and cost advantages of carbon steel, serving as critical materials for pressure vessels and large chemical equipment. However, large‑format and thick‑cladding products have long suffered from industry bottlenecks such as unstable interfacial bonding and low ultrasonic testing pass rates, restricting the batch application of domestic materials in large chemical projects. This targeted technical research addresses the quality control difficulties of bonding interfaces for large plates. The product stability and testing indicators meet the requirements of high‑end equipment. It can steadily supply high‑end clad plates for hydrometallurgy and large petrochemical equipment, greatly expanding the import substitution space of domestic explosive welded clad plates in major chemical projects.
Across the industry, R&D on super‑large‑size titanium‑steel clad plates is ongoing. Technologies for forming long titanium‑steel clad plates, interfacial bonding regulation and non‑destructive testing keep being upgraded. The products are suitable for core components such as large heat exchangers, tube sheets and pressure vessels, matching the large‑scale and integrated development trend of petrochemical and metallurgical equipment.
Explosive bonding is a core process for dissimilar metal cladding. This technical breakthrough of high‑end titanium‑steel clad plates reduces the reliance of domestic major equipment on imported materials and supports cost reduction and efficiency improvement for the heat exchanger and pressure vessel industrial chain. As an important segment of high‑end metal composite materials, titanium‑steel clad plates are continuously evolving toward larger sizes, thicker cladding layers and higher stability.
With a mature explosive bonding process system, we keep focusing on the R&D and manufacturing of titanium‑steel, nickel‑steel and stainless steel clad plates, as well as copper‑steel clad tube sheets. Following the latest industry technological progress, we continuously optimize interfacial bonding control and precision machining capacity. We provide reliable metal composite material solutions for customers in chemical, marine and pressure vessel sectors, and jointly promote the localization of materials for high‑end equipment.
