摘要：In the current study, mechanical properties including tensile strength, impact strength, fracture toughness and creep-rupture strength for ex-service 12Cr1MoV steel and new and ex-service 10CrMo910 steel are collected, analysed and compared with each other. Comparison between new and old materials shows properties have degraded by long-term high-temperature service; while comparison between 12Cr1MoV steel and 10CrMo910 steel indicates the former is better than the latter in fracture toughness and creep-rupture strength.
