Various types of heat-resisting steels and alloys are in service as tube and pipe in high temperature section of power generation and chemical plants. For improving efficiency of the total system and for meeting requirements to cope with “dirty” fuels in some cases, these steels and alloys nowadays are being used in much severer conditions than before in terms of high temperature strength and corrosion resistance.
This paper describes the recent research and development trends of new heat-resisting steels and alloys for boiler tubes and pipes, fast breeder fuel cladding tubes, high temperature gas cooled reactor heat exchanger tubes and ethylene plant cracking tubes.
