A silvery metal that resists corrosion. Uses. About 80% of the vanadium produced is used as a steel additive. Vanadium-steel alloys are very tough and are used for armour plate, axles, tools, piston rods and crankshafts. Less than 1% of vanadium, and as little chromium, makes steel shock resistant and vibration resistant.

XRD patterns for vanadium-titanium magnetite. ISIJ International, Vol. 58 (2018), No. 4. was shown in Figs. 5–6. In the shaded area, metal and slag can be well separated.
