Abstract

1. Constructional steel which has high fatigue strength, possesses good weldability up to a carbon content of 0.3% and is resistant to atmospheric corrosion, characterised in that in addition to iron it contains at most 1.6% (by weight) of C, 0.3 to 3.0% (by weight) of Mn and/or of Ni, at most 1.8% (by weight) of Si, 0.6 to 4.0% (by weight) of Cu, at most 3.0% (by weight) of Mo and/or Co, 0.02 to 0.4% (by weight) of Nb and/or of V, at most 0.006% (by weight) of B, at most 0.4% (by weight) of Zr and/or of Be, 0.02 to 0.2% (by weight) of Al, 0.005 to 0.2% (by weight) of N, at least 0.0001% (by weight) of Ca and at most 0.25% (by weight) of Ce and/or of Pb, and up to 0.1% of sulphur.
