摘要：CrMo910 Main steam piping exposed at elevated temperature in the creep range was studied in present paper.The properties including tensile strength,toughness and creep-rupture strength of this component had been degraded by 21 years′ service.Material damage was characterized by spheroidization of carbides.Creep-rupture data had been analyzed and remaining life of nearly 80,000 hours could be expected.
