Abstract
A tubular reinforcing element for the interior of vehicle doors is made from a steel tube having a carbon content of 0.14-0.18%, 0.15-0.30% silicon, 1.60-1.80% manganese, 1.90-2.10% chromium, 0.45-0.60% molybdenum and at least 0.015% aluminum. This tube is annealed at 900.degree.-930.degree. C. and then aircooled. Thereafter the portions of the tube which are to be deformed are heated to above the temperature of the alpha-gamma phase change (A.sub.3 on the iron-carbon equilibrium diagram), then deformed to the desired shape and aircooled. All percentages are by weight.
