摘要	Three groups of specimens with different hydrogen contents (c) were obtained from three different heat treatment procedures: quenched and tempered (specimen QT, 0.6 x 10(-6)), annealed at 380 degrees C in a vacuum after QT (specimen VA, 0.2 x 10(-6)) and treated by high-pressure thermal hydrogen charging (HPTHC) after QT (specimen HPTHC, 2.5 x 10(-6)). SEM observation showed that the crack initiation sites are all at internal inclusion clusters under high cycle fatigue. The fatigue strength (sigma(w)) decreased according to sigma(0) - alpha exp(c) law with the increase of c. Basquin exponent in Basquin equation changed distinctly with the increase of c.
