Diffusible hydrogen or non‐diffusible hydrogen can decrease the fatigue strength of high‐strength steels. The hydrogen influence factor f (C) describes the hydrogen damage level of fatigue strength. Fatigue strength decreases with increasing non‐diffusible hydrogen content in the range 1 ppm < C i < 3.0 ppm. Fatigue strength decreases significantly with increasing diffusible hydrogen content in the range 1 ppm < C r < 3.0 ppm, but shows almost no obvious change in the range 3.0 ppm < C r < 10.0 ppm.
