"Find out all about this," I told him. "That is the kind of material we ought to have in our cars."
He found eventually that it was a French steel and that there was vanadium in it. We tried every steel maker in America—not one could make vanadium steel. I sent to England for a man who understood how to make the steel commercially. The next thing was to get a plant to turn it out. That was another problem. Vanadium requires 3,000 degrees Fahrenheit. The ordinary furnace could not go beyond 2,700 degrees. I found a small steel company in Canton, Ohio. I offered to guarantee them against loss if they would run a heat for us. They agreed. The first heat was a failure. Very little vanadium remained in the steel. I had them try again, and the second time the steel came through. Until then we had been forced to be satisfied with steel running between 60,000 and 70,000 pounds tensile strength. With vanadium, the strength went up to 170,000 pounds.
Having vanadium in hand I pulled apart our models and tested in detail to determine what kind of steel was best for every part—whether we wanted
