The hydrogen embrittlement characterization of UNS G43406 and UNS K92580 was conducted using a rising step load bend test and potentiodynamic scans. A relationship between KIscc and open circuit potentials of these steels at similar hardnesses was shown. Potentiodynamic scans were used to explain this relationship in light of the hydrogen ion reaction in acidified environments. Methods for the mitigation of hydrogen embrittlment in high strength steels are discussed.
