Description
Vanadium (CAS 7440-62-2, EC 231-171-1, formula V) is a transition metal element, also referenced under trade designations such as VN 200 and Vanadium-51, and catalogued under MeSH ID D014639. It carries no assigned E-code and is classified within the Salts & Minerals category.
In steel and titanium alloy production, vanadium acts as a grain refiner and carbide former, increasing tensile strength and hardness in automotive and aerospace structural components. As a catalyst in sulfuric acid manufacture, vanadium pentoxide derived from the element facilitates the oxidation of sulfur dioxide to sulfur trioxide, driving conversion rates above 98%.
Vanadium is supplied as metal turnings or solid pieces and is subject to REACH registration requirements for industrial quantities within the EU. Procurement should confirm grade specification and purity certificates prior to ordering, as material standards vary by end-use sector, particularly for energy storage and refining applications. HS code 8112 92 91 applies.
