Description Of Zirconium Rod & Bar | Zr702 UNS R60702 ASTM B550 Supplier
Zirconium Rod & Bar are solid cylindrical or rectangular products manufactured from zirconium and zirconium alloys through vacuum arc remelting (VAR), forging, hot rolling, cold finishing, and precision machining. As a direct ASTM B550 zirconium rod supplier, we produce these materials in unalloyed zirconium grades Zr702 (UNS R60702) and Zr704 (UNS R60704), as well as zirconium-niobium alloy Zr705 (UNS R60705). These materials offer a unique combination of properties that make them indispensable in the most demanding environments.
Zirconium possesses outstanding corrosion resistance in hydrochloric acid, sulfuric acid, nitric acid, acetic acid, and strong alkalis. It is immune to stress corrosion cracking (SCC) and highly resistant to pitting and crevice corrosion. Its low thermal neutron absorption cross-section makes it the material of choice for nuclear reactor components. Additionally, zirconium has good formability and weldability, allowing it to be machined, bent, and welded into complex shapes.
Our zirconium rods and bars are available in diameters from 6mm to 150mm, with custom sizes upon request. Surface finishes include pickled, machined, and polished. The material complies with ASTM B550 / ASME SB-550, the standard specification for zirconium and zirconium alloy bar and wire. Typical applications include chemical processing equipment, nuclear reactors, heat exchangers, condensers, reaction vessels, piping, pumps, valves, medical devices, and aerospace components. We are a direct supplier with ISO 9001 certified manufacturing, offering full traceability and competitive pricing.
