Vanadium processing | Britannica
· Vanadium processing, preparation of the metal for use in various products.. Vanadium (V) is a grayish silver metal whose crystal structure is a bodycentred cubic (bcc) lattice, with a melting point of 1,926° C (3,499° F). The metal is used principally as an alloying addition to highstrength lowalloy (HSLA) steels and, to a lesser extent, in tool steels and iron and steel castings.
