On June 24, 1981, the US Department of Commerce conducted an anti-dumping investigation against sorbitol originating in France. The customs code for the product involved was 29054400. On February 12, 1982, the US Department of Commerce made an anti-dumping final ruling on the case and ruled that the case was involved in France. The dumping margin of enterprises is 2.90% to 5.50%. On July 1, 2009, the US Department of Commerce conducted an anti-dumping sunset review of the case. On November 3, 2009, the US Department of Commerce made a final review of the anti-dumping sunset review and ruled that the dumping margin of French-affected companies was 2.90%.
Niobium is a kind of gray metal with luster. High purity niobium has a high ductility, but it becomes hard with the increase of impurity content. Niobium has a very low capture cross section for thermal neutrons and is therefore useful in the nuclear industry.
Niobium and niobium-based alloys feature a high melting point, high-temperature strength, small cross-section of thermal neutron capture, high corrosion resistance, the lowest density of heat-resistant metals (tungsten, molybdenum, tantalum, niobium), a high level of manufacturability and weldability.
The high level of ductility, high-temperature strength, corrosion and chemical resistance of niobium make it possible to use it in the production of high-strength low-alloy steels and heat-resistant alloys.
high purity niobium bars, niobium tubes, niobium sheets,etc
