51318-10977- Effect of Charging Method on the Evaluation of HE Susceptibility for High-strength Stru

Available for download

We evaluated hydrogen embrittlement (HE) susceptibility of three high-strength alloys including a martensitic stainless steel, a high-strength carbon steel, and a duplex stainless steel. HE testing was according to the Incremental Step Loading Technique of ASTM F1624.

Susceptibility to hydrogen embrittlement (HE) is an ongoing concern for high-strength structural bolts.

We evaluated the HE susceptibility of three high-strength alloys including a martensitic stainless steel, a high-strength carbon steel, and a duplex stainless steel. We conducted HE testing according to the

Incremental Step Loading Technique of ASTM F1624. In order to charge the specimens with hydrogen, we used an electrochemical charging method and compared charging the specimens prior to testing to in situ charging during testing. We determined that in situ charging results in improved penetration of hydrogen into the test specimen compared to precharging, and thus provides a more accurate evaluation of the HE susceptibility of structural bolts.
