The hydrogen induced crack resistance test is a test with a complex process and a long test period in a hydrogen sulfide saturated solution environment. The method is a commonly used evaluation method for evaluating the hydrogen embrittlement resistance of pipeline steel, high-pressure vessel steel and the like. The standards mainly used are GB/T8650-2015, GB/T4157-2017, NACE TM0284-2016 and the like. However, no matter what standard the hydrogen induced cracking resistance test is carried out, the test is difficult to ensure to be effective, and the evaluation result is correct and reliable. Because the test conditions of the hydrogen induced crack resistance test are strict, the factors to be controlled are more, the period is long, and the like, the test can fail if the operation of which step is careless.
And at present, no specific method is available for judging whether the test is effective. The problem is particularly obvious in the production test of the hydrogen embrittlement resistance of pipeline steel and high-pressure vessel steel. The specific expression is that even if the crack test is strictly executed according to the standard, the test steel sample hardly has hydrogen-induced cracks, and whether the test is effective or not is difficult to judge under the condition, and whether the evaluation result is correct or reliable is not dependent. In view of this, it becomes necessary to find a method capable of judging whether the hydrogen induced crack resistance test is effective.
