A good deal of Vanadium alloy is used, and this is made in America.

Vanadium steel is used throughout the construction of the car.

Vanadium as an alloy increases the elastic limit, making the steel stronger, tougher and harder.

Nickel steel rods may be used for parts requiring great strength, but vanadium alloys are very difficult to handle.

Vanadium is detected by the red colouration produced by passing sulphuretted hydrogen into ammoniacal solutions for some time.
