摘要：
The effect of impurities such as deliberate additions of P, Sb, and Sn on the threshold stress intensity for cracking in H//2S (K//I//S//C//C) was investigated at various yield strength levels on a low alloy steel similar to 4340. The general conclusions are that the results of the study indicate that the K//I//S//C//C of steels is affected by impurities, yield strength, and H//2S both directly and indirectly via interactive mechanisms.
