Based on the data of the literature for intercrystalline stress corrosion cracking (SCC) and hydrogen embrittlement of the high‐strength steel AISI 4340, determination of the so far unknown effects of tempering treatment around the low temper‐martensite embrittlement range (between 175 and 285°C) on the fracture appearance. Variation of the stress intensity and applied potentials in 0.5 N NaCI solution. Discussion on obtained fractographs for a better understanding of the SCC mechanism.
