摘要： A motor vehicle tire is reinforced by at least one carbon steel band that has a very low carbon content and high strength in the work-hardened state The carbon steel comprises (% by weight) between 0.05% and 0.4% of carbon, between 0.5% and 4% of manganese, between 0.1% and 2.5% of silicon, optionally (i) less than 1.5% of aluminium, (ii) less than 0.5% of each of the metals boron, chromium, cobalt, copper, molybdenum, nickel, niobium, titanium, tungsten, vanadium, and zirconium, and (iii) less than 0.05% of each of the elements phosphorus, sulfur, nitrogen, or rare earth, and the rest is made up of iron and inevitable impurities resulting from the smelting. The microstructure of the work-hardened carbon steel is mainly martensitic or ferritic-martensitic. The strength, denoted Rm, of the strip is greater than 1200 MPa and its elongation at break, denoted At, is between 1% and 5%.
