Yes, Zirconium bars can be welded. It requires specialized techniques such as gas tungsten arc welding (GTAW) to ensure good weld quality, as it is highly reactive at elevated temperatures.
To maintain zirconium rods, keep them clean and free of contaminants. Store in a dry, cool environment. Avoid mechanical damage and ensure proper handling to prevent oxidation or corrosion.
Zirconium bars are generally resistant to galvanic corrosion due to their high corrosion resistance properties. However, when paired with more reactive metals, galvanic corrosion may still occur.
Zirconium Bars and Rods find extensive use in industries such as chemical processing, nuclear, aerospace, and medical fields. They are commonly utilized in heat exchangers, chemical vessels, piping, cladding for nuclear reactors, and corrosion-resistant structural components. Their ability to withstand aggressive acids, high temperatures, and harsh environments makes them perfect for specialized equipment and high-performance tools. Additionally, zirconium rods and bars are employed in laboratory equipment, seawater handling systems, and metallurgical applications. These products deliver the reliability and performance needed for critical tasks.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
