Abstract (en)

[origin: WO2017103515A1] Disclosed is a motor vehicle tire reinforced by at least one carbon steel strip that has a very low carbon content and high resistance in the cold-worked state, characterized by the following: - the carbon steel comprises (in percent by weight) 0.05% to 0.4% carbon, 0.5% to 4% manganese, 0.1% to 2.5% silicon, optionally (i) less than 1.5% aluminum, (ii) less than 0.5% of each of the metals boron, chromium, cobalt, copper, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, et (iii) less than 0.05% of each of the elements phosphorus, sulfur, nitrogen or rare earth metal, the remainder consisting of iron and inevitable impurities resulting from the process; - the microstructure of the cold-worked carbon steel is primarily martensitic or ferritic-martensitic; - the resistance Rm of the strip is greater than 1200 MPa, and its elongation at break At ranges from 1% to 5%.
