Pickling with hydrochloric acid is a standard method to clean steel surfaces before hot-dip galvanizing. While hydrogen formed during pickling does not adversely affect the mechanical properties of normal low-strength steels, high-strength low-alloy (HSLA) steels can suffer severe damage from hydrogen penetration. This study investigates the effect of pickling on HSLA steels by employing a modified Devanathan-Stachurski method for measuring hydrogen entry. An electrochemical cell was constructed with hydrochloric acid on one side and NaOH solution on the other, ensuring no protective coating was required on the anodic side of the sample. The results indicated that the rate of hydrogen penetration and exit from the steel was lower in higher strength steels, suggesting a reduced susceptibility to hydrogen damage. This research emphasizes the importance of understanding hydrogen behavior in HSLA steels during pickling to mitigate risks such as brittle failures during service. The findings contribute valuable insights for the manufacturing and application of HSLA steels, highlighting the trade-offs in performance and safety associated with their use.
