Internal hydrogen embrittlement of pre-cracked, cadmium-plated AISI 4340 high strength steel with sustained load tests and incremental step-loading tests

•Threshold stress intensity for onset of internal hydrogen embrittlement (IHE) is studied.•The incremental step-loading method is used on pre-cracked compact samples.•Compact samples are less sensitive to IHE than circumferentially-notched samples.•Hydrogen is located in or close to the coating for...
