By the middle of the 20th century, a term appeared in chemical science - metals of strategic importance. It meant a group of elements whose physicochemical properties made it possible to use them in the production of the military-industrial complex. We are talking about metals such as chromium, tantalum, niobium, molybdenum and tungsten. Vanadium, whose properties we will consider in this article, also rightfully occupies one of the central places among the metals used in modern engineering, ferrous metallurgy
