摘要：

The hydrogen permeability and hydrogen content on cathodic charging in HSLA 80 steel are marginally higher than those in the HSLA 100 steel. The difference can be attributed to the compositional and structural variations in these two steels providing a variation in hydrogen trapping and hydrogen repelling effects. The higher breakthrough time in HSLA 100 is indicative of a lower diffusivity of hydrogen compared to HSLA 80. The total hydrogen content in the uncharged HSLA 80 was found to be 0.89 ppm and in the HSLA 100 was 0.48 ppm.
