Influence of working condition on properties of superheater steel pipe (ASTM grade P11)

Investigation of the superheater steel pipe must be considered in order to predict their remnant life of the steel in the thermal power plant. The lifetime is thought to mainly depend on working condition of high temperature and pressure of the steam. To understand the workability of the steel, this paper studied mechanical properties and microstructure changes with time of the pipeline steel (ASTM grade P11) working on the high temperature and pressure.
