Ferrovanadium is an alloy of iron and vanadium used for modifying the microstructure of steel, increasing impact strength, hardenability and tempering resistance, and improving stress resistance. Ferrovanadium is supplied in lumps or in the form of crushed and sieved particles. Fractional composition of the supplied material depends on the needs of the consumer and can be provided in the range from 0 to 100 mm.
