The Moldavian Metallurgical Combine has mastered the production of quality vanadium-bearing high-carbon wire rod 5.5-12.0 mm in diameter. Strengthening of the grain boundaries of the steel and its dispersion-hardening significantly increase the strength properties of wire rod made of steel that has been microalloyed with vanadium, while the ductility of the product also remains high. Tests in which vanadium-bearing high-carbon wire rod 5.5-12.0 mm in diameter was drawn into 3-7-mm-diam. wire were conducted at hardware plants and showed that the wire rod is well-suited for the production of wire used in the reinforcement of prestressed concrete structures.
