Overview of Zr/Steel Clad Plate: Refractory Metal Clad Plate for High Temperature Applications
Tungsten is a metallic element with the element symbol W and atomic number 74. It is located in the VIB group of the sixth period of the periodic table of elements. In nature, tungsten mainly exists in the form of hexavalent cations. Its ionic radius is small, it has strong polarization ability, and it is easy to form complex anions.
When preparing pure tungsten or tungsten alloy, the main methods include powder metallurgy, smelting (including electron beam melting, vacuum melting, plasma beam melting) and chemical vapor deposition.
Feature of Zr/Steel Clad Plate: Refractory Metal Clad Plate for High Temperature Applications
The thermal expansion coefficient of tungsten is very low, only 4.5×10^-6 m/mK, so it has good thermal stability. These properties make tungsten widely used in manufacturing high-temperature components and reliable heat detectors.

Zirconium/Steel Clad Plate: A Robust Solution for Extreme Heat Resistance
In the realm of high-temperature engineering applications, the demand for materials capable of enduring intense heat and maintaining structural integrity is paramount. One such innovative material that has emerged as a reliable choice is Zirconium (Zr) clad steel plate. This composite material combines the exceptional heat resistance of zirconium with the strength and durability of steel, offering a versatile solution for various industries.
Zirconium, a refractory metal from the lanthanide group, boasts an extraordinary melting point of around 4422°C (8292°F), making it an ideal candidate for handling elevated temperatures. Its low thermal expansion coefficient ensures minimal dimensional changes under extreme heat, reducing the risk of deformation or cracking. Furthermore, Zr’s excellent corrosion resistance, particularly in molten salts and alkalis, safeguards against degradation even in harsh environments.
The steel core in Zr/steel clad plates serves as a strong backing, providing structural integrity and mechanical strength. Steel’s high tensile strength and ductility make it an efficient load-bearing component, while its compatibility with techniques ensures ease of fabrication and repair when needed. The clad layer thickness can be tailored to meet specific application requirements, ranging from thin layers for improved heat transfer to thicker ones for enhanced protection.
One key advantage of Zr/steel clad plates is their ability to maintain their properties over extended periods, which is crucial in industries like power generation, aerospace, and chemical processing. In nuclear reactors, for instance, these plates can withstand the intense heat generated by nuclear reactions, safeguarding the reactor’s integrity and minimizing the risk of radioactive contamination. Similarly, in gas turbine engines, they protect internal components from thermal stresses and erosion caused by high-velocity gases.
Another significant benefit is the potential for cost savings. By using Zr/steel clad plates instead of solid zirconium or pure steel, engineers can leverage the benefits of both materials without incurring the high cost associated with pure zirconium. This makes it an economically viable option for applications where weight reduction and cost efficiency are critical factors.
However, it’s essential to note that the selection of Zr/steel clad plates requires careful consideration of factors such as compatibility with other materials, creep resistance, and fabrication processes. The manufacturing process itself involves depositing a thin layer of zirconium onto a steel substrate through techniques like vacuum deposition or electroplating, followed by heat treatment to bond the two materials securely.
In conclusion, Zr/steel clad plates represent a cutting-edge technology that addresses the challenges of high-temperature environments with a unique combination of properties. Their heat resistance, durability, and versatility make them a preferred choice for industries operating under demanding conditions. As advancements continue in material science and manufacturing processes, Zr/steel clad plates are poised to play an increasingly significant role in the future of engineering and technology.
