1. Application: Ferrovanadium Alloy is an important additive in iron steel industry.2. Properties: Vanadium can improve the strength, flexibility, extensibility, heat resistance of steel. Vanadium is the main refining grain in common low alloy steel to improve the strength of steel and avoid aging of steel. Vanadium is the refining grain in structural alloy steel to increase the strength and flexibility of steel. Vanadium is mixed with chromium and manganese in spring steel to increase the flexibility limit of steel and improve its quality. Vanadium mainly refines the structure and grain of steel to increase the stability of tempering steel to reinforcing secondary hardening and improve its abrasion resistance to prolong its service life. Vanadium plays a helpful role in heat resistant steel and antihydrogen steel.3.
