As fatigue crack life method for a low alloy steel material in contact with the high-pressure hydrogen in the high-pressure hydrogen environment, under high pressure hydrogen environment, to obtain a crack growth threshold stress intensity factor (K
IH
-R) through enhanced load test for the low alloy steel material , by use of said crack growth threshold stress intensity factor obtained
(IH
-R K) estimates the fatigue crack acceleration start point
(T K
max) of the low alloy steel material. The high-pressure hydrogen environment of enhancing the load test, and the same pressure and a high pressure hydrogen environment having the same atmosphere as in a high pressure hydrogen environment in which to estimate the K
T
max, test temperature tolerance between both environments is ± 5 ℃.
