The material is also strong so that the UNS R03400 Bar is used in nozzles of the airplane engines, aerospace industrial applications, nuclear reactors and in anti-corrosive parts of strong acidic processing plants. The thickness and length of the bars range with the width of the bars. The widths range from 15mm to 60mm and the lengths vary from 600mm to 1500mm. There are niobium grade 1 and grade 2. The difference is in the material composition.


The ASME SB393 Niobium Hex Bar as well as round bar has impurity contents such as tantalum, oxygen, nitrogen, carbon, silicon, iron, tungsten, molybdenum, titanium, aluminum, copper, chromium, nickel and zinc in the composition. The Hot Rolled Niobium Round Bar and other types have more than 99.95% niobium in the composition. The specification for the bars is ASTM B392-98. The diameter range is 4mm to 100 mm for round bars whereas the Niobium Square Bar products are also available with us. Please feel free to contact us for more product information and pricing.
