The mechanical behaviourunder fatigue-creep interaction (FC) of 12Cr1MoV steel and all the information, in-cluding fracture life, strain rate and main factors controlling fracture model (FF,FCF, CFF,FCC, CFC, CC), may be described on the map. The 12Cr1MoV steel has weakresistance at 588℃, which is in the ratio of 1 to fatigue resistance. An FC regionoccurs widely on the map of the steel, saying, the FCC (fatigue crack nucleation,creep propagation and fracture) fracture model may be relatively easily appeared.After the steel was in the service for steam pipe at 540℃ for 2×10~5 h, the FCproperties are remarkably reduced and the fracture model changes too.
