Yes, Hastelloy B2 rods can be welded. However, it requires proper techniques and filler materials to avoid cracking due to their sensitivity to heat-affected zones.
Hastelloy B2 bars offer exceptional resistance to hydrochloric acid and other corrosive environments, along with excellent weldability and high strength. They are highly resistant to pitting, stress corrosion, and localized corrosion.
Hastelloy B2 rods are available in various sizes, ranging from small diameters to larger rods, with common diameters including 0.125 inches to 4 inches. They typically come in a polished or cold-drawn finish, depending on the application requirements.
Hastelloy B2 Bars and Rods find extensive use in industries that deal with highly corrosive and reducing environments. In the chemical and petrochemical sectors, they are utilized in reactors, heat exchangers, and process vessels that come into contact with hydrochloric, acetic, and phosphoric acids. The pharmaceutical industry relies on them for equipment that demands contamination resistance. In power generation, they are employed in condensers, piping, and boiler systems that are exposed to harsh chemicals. Additionally, these bars are well-suited for marine applications where resistance to localized corrosion is crucial. Their durability and performance make them an excellent choice for long-term, high-stress operations in tough environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
