In the field of high-end equipment manufacturing, titanium steel clad panels have become a key material innovation with their unique "steel reinforced titanium skin" structure. As a representative of layered metal clad materials, it perfectly combines the excellent corrosion resistance of titanium with the excellent mechanical properties of steel, while significantly reducing the amount of precious metals used, achieving cost savings of 30% -50%. Hunan Phohom New Materials Technology Co., Ltd. continues to promote technological innovation and industrial upgrading in this field with its internationally leading explosive composite technology.
Analysis of Core Preparation Process
The manufacturing process requirements for titanium steel clad plate are extremely high, and the mainstream technologies currently include three directions:
Explosive composite method: By precisely controlling the detonation of explosives, high-speed impacts of several kilometers per second are generated, causing atomic level cold bonding between titanium and steel plates in an instant, forming a unique wavy interface. This method combines strength close to the base metal and is particularly suitable for thick plate production.
Rolling composite method:
Thick plate rolling: Using titanium steel titanium symmetrical billet, electron beam welding sealing is carried out in a high vacuum environment, and metallurgical bonding is achieved through segmented heating (500-900 ℃) and multiple passes of rolling (total reduction of 60-70%).
Continuous hot rolling: specially designed for thin plates, it is continuously rolled after arc welding in atmospheric environment to produce composite materials in the form of coils.
Innovative intermediate layer technology: The nickel chromium vanadium clad intermediate layer technology (steel/nickel/chromium/vanadium/titanium structure) developed by Phohom New Materials can effectively suppress the formation of brittle intermetallic compounds, making the interfacial shear strength break through the 370MPa threshold, far exceeding the traditional process's 210-300MPa.
Deep expansion of multi domain application scenarios
In the field of energy and chemical engineering, titanium steel clad plates are irreplaceable in core equipment such as million ton PTA oxidation reactors and nuclear power condenser tube plates. Its high temperature and pressure resistance, as well as corrosion resistance, ensure the long-term stable operation of the equipment in harsh environments, increasing its service life by 2-3 times.
Ocean and Environmental Protection Engineering: As a key material for seawater desalination equipment and anti-corrosion lining for marine platforms (thin plates with a thickness of less than 5mm), titanium steel clad plates exhibit excellent resistance to seawater erosion and ion leaching, achieving environmentally friendly protection.
Emerging strategic industries:
Semiconductor manufacturing: used for lining electronic grade polycrystalline silicon reduction furnaces
New energy equipment: key components of energy storage batteries
Vacuum salt production: The evaporation chamber made of 360 ton titanium steel composite plate significantly extends the tank cleaning cycle
As China's equipment manufacturing industry moves towards high-end, the market size of titanium steel clad panels has exceeded 1.5 billion yuan, showing explosive growth in fields such as nuclear power localization (with an annual demand of 924 tons) and ocean engineering. Hunan Phohom New Materials, as a national level specialized and innovative "little giant" enterprise, provides global customers with layered metal composite material solutions with higher bonding strength and better dimensional accuracy through continuous technological innovation (with more than 50 patent applications), promoting high-end equipment manufacturing into a new era.
