| Abstract: | The development and classification of heat - resistant steels are introduced.Through a case study on perlite steel 12Cr1MoV widely used in thermal power plants and petrochemical industry,the causes of microstructure transformation and performance deterioration in high - temperature service are analyzed.The discard standards for 12Cr1MoV steel in service are summarized.These are very important for the failure analysis of pressure pipelines,service life evaluation and prevention of large safety accidents. |
