The creep and rupture properties of steels were investigated at 1000 deg F in an environment of argon at 50 psig pressure and hydrogen at 900 psig pressure. An SAE 1020 steel, a 0.5 percent Mo-steel, and a 1 percent Cr-0.5 percent Mo steel were used as test materials. The strength of the steels was lower and the creep rate higher in hydrogen than in argon. The data are discussed in respect to the effect of stress on the rate of hydrogen attack.
