The Effect Of Impurities And Strength Level On Hydrogen ...

The effect of impurities on the threshold stress intensity for cracking in H 2 S (K{ISCC}) has been investigated at various yield strength levels for a low alloy steel. Results show that the effect of impurities on K ISCC is a function of the yield strength level. At low yield strength levels the K ISCC of the steel is lowered markedly due to additions of impurities.
