A hydrogen embrittlement evaluation test was conducted with 1180MPa grade ferrite-martensite type dual phase steel (1180DP) for automotive use by the Conventional Strain Rate Test (CSRT) method. The critical condition of hydrogen embrittlement was compared with those conditions obtained by U-bending and drawn cup methods. In the CSRT test, a notched sample was used and tensile speed was set at 1mm/min. Critical conditions were plotted of the strain and diffusible hydrogen content under stress of 900MPa. The condition of hydrogen embrittlement obtained by the CSRT method was lower than that obtained by the other two methods. A discussion on the...
