Ferronioby – the alloying alloy of iron and niobium (about 60% of Nb, other Fe and impurity). Ferronioby enter in corrosion - proof chromonickel became for prevention of their intercrystalline corrosion and destruction and in steel of other types for improvement of their properties. Entered in constructional became, ferroniobiya improves their svarivayemost, prevents corrosion of a welded seam, increases durability and plasticity of steel. Niobium increases plasticity, corrosion resistance, durability and a svarivayemost became. Also, ferroniobiya it is widely used for production of electrode coverings, in the steel - smelting and foundry industry. Ferronioby deliver in pieces or in the form of the shredded and sifted particles.
