Abstract 30Cr2Ni4MoV and 30Cr2MoV steels presented blue brittleness near 230℃ and 180℃, respectively. The susceptibility of stress corrosion cracking (SCC) for this kind of steels in aqueous solution at various temperatures is very low except near blue brittleness temperature. Near blue brittless temperature, there is a strong interaction between the dynam-ic strain aging, which results in blue brittleness, and SCC, resulting in a steep enhancement of the susceptibility of SCC.
