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 their place in industries where corrosion resistance and material reliability are paramount. They are commonly used in chemical and petrochemical equipment, including reactors, heat exchangers, valves, and pumps. In the nuclear industry, they play a crucial role in fuel cladding and structural components due to their low neutron absorption properties. Additionally, they are utilized in aerospace components, medical and surgical instruments, marine hardware, precision fasteners, and specialized research and high-temperature industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
