A vehicle is armored the steps of sequentially making a steel plate with a thickness of 4 mm to 15 mm of by weight 0.2 to 0.4% carbon, 0.3 to 0.8% silicon, 1.0 to 2.5% manganese, max. 0.02% phosphorous, max. 0.02% sulfur, max. 0.05% aluminum, max. 2% copper, 0.1 to 0.5% chromium, max. 2% nickel 0.1 to 1% molybdenum, 0.001 to 0.01% boron, 0.01 to 1% tungsten, max. 0.05% nitrogen, and balance iron and impurities. This plate is heated to above the AC3 temperature and deformed without cooling in a press. While still in the press, the steel plate is cooled and cured. Then the deformed and cured steel plate is taken out of the press and mounted on the motor vehicle without significant further working or shaping.

The method defined in claim 1, further comprising the step of tempering the plate in the press. 3. The method defined in claim 1 wherein the ratio of copper to nickel is 1:1. 4. A shaped armor steel plate made by the method of claim 1. 5. The shaped armor steel plate defined in claim 1 wherein the plate is formed into a piece of a vehicle body. 6. The shaped armor steel plate defined in claim 5 wherein the plate is deformed through angle greater than 4��. 7. The shaped armor steel plate defined in claim 4 wherein the plate has a ratio on nickel to copper equal substantially to 1:1.
