摘要
Heat resistance of steels grades 10Kh9MFB-Sh, 10Kh9V2MFBR-Sh, 10Kh9K3V2MFBR-Sh, and 10Kh16N16V2MBR is studied by experiment in the range 600 – 700°C with oxidation by air, Na2SO4, and ash from Na2SO4 and V2O5. The permissible operating temperature is calculated for pipes made from the test steels with respect to high-temperature strength and heat resistance. Steel grades are selected for the heating surfaces of a new generation of coal-fired boilers with supercritical steam parameters, i.e., pressure 30 MPa and temperature 600 – 620°C. © 2014, Springer Science+Business Media New York.
