Abstract (en)

[origin: WO2004048628A1] The invention relates to a steel alloy that consists, in percentages by mass, of: 0.09 0.13 % carbon (C); 0.15 0.30 % silicon (Si); 1.10 1.60 % manganese (Mn); a maximum of 0.015 % phosphorous (P); a maximum of 0.011 % sulfur (S); 1.00 1.60 % chromium (Cr); 0.30 0.60 % molybdenum (Mo); 0.020 0.050 % aluminum (AI); 0.12 0.25 % vanadium (V), and; as the remainder, iron as well as impurities that result during smelting. This steel alloy is used as a material for tubes, which are air-hardened or both air-hardened and tempered, for producing thick-walled tubular parts for motor vehicles.
