Application of vanadium in the steel industry

  Vanadium in iron and steel industry is mainly used as alloying additives. Approximately 85% of the world's vanadium for the steel industry. United States carbon steel and high-strength low-alloy steels is the largest iron and steel industry the amount of vanadium in steels, accounting for more than 60% of the amount of vanadium steel industry, followed by the high-alloy steel. Although vanadium carbon steel consumption during the recession in the early 90 's economy declined, but since then, gradually increase the amount. In contrast, wuhu renben vanadium steel consumption has been declining. High alloy steel and vanadium tool steel after 92 rebound and gradually declining
The role of vanadium in steel refine steel and grain. Enhance the grain coarsening temperatures lead to lower of thermal sensitivity of the steel to improve the strength and toughness of steel. Vanadium dissolved in austenite at high temperatures can increase the hardenability of steel. In addition, vanadium increases tempering stability of hardened steel, and secondary hardening effect. Vanadium as a strong carbide forming elements and precipitation hardening agent, a strong strength and impact resistance at high temperatures, corrosion resistance and weldability.
