Niobium round bar

Niobium Round Bar

These round bars increase in demand are increasing day by day in the global industrial market due to its high melting point and excellent cold working performance. Niobium round bar display superior oxidation resistance and strong mechanical properties due to addition of Zirconium to Niobium. ASTM B393 UNS RO4210 round bar are highly corrosion resistant to various aggressive corrosions caused by toxic acids such as hydrochloric, sulfuric and nitric acid. The round bars are available in different lengths ranges from 200-9000 mm and it is also available in customized lengths as per your requirements. Due to its high tensile strength of 287 MPa and supreme malleability UNS R03400 bar offer outstanding functionality.
