Abstract The accidental failures of fastening bolt(M33) made of Ultra-high strength steel 3OCrMnSiNi2 were investigated by fraetography. The result showed that it was stress corrosion fracture in water or БФ-2gum. The K_(ISCC) and da/dt of 3OCrMnsiNi2 steel in water and БФ-2 gum were measured by the constant load and constant displacement specimen of L-C and R-C direction. For three low alloy steels, the influence of heat treatment on the K_(ISCC) and da/dt were investigated. The threshold value of stress corrosion cracking of the notch specimen K_(ISCC)(ρ)was measured by modified WOL type notched specimens of various tip radius ρ. The result was as follows where A and B are constants for the speejfje materials. For 3OCrMnSiNi2 (T. S.=158OMPa), the parameters A, B and ρ are 21.7 MPa m~(1/2), 4180 MPa and 0.027 mm respectively. The accidental failures of the fastening bolt with pre-crack or no crack are quantitatively analyzed by linear elastic fracture mechanics. According to these results. preventive measures to avoid failure of the fastening bolt have been suggested.
