Recent Research and Development Trends of Heat Resistant Steels for Power Boilers

Abstract

Various types of heat-resistant steels are in service as tubes and pipes in high temperature section of fossil fired boilers.
For improving thermal efficiency, the application of new heat-resistant steels with superior high temperature strength and corrosion resistance are being required.
This paper describes the recent research and development trends, development philosophy and characteristics of new heat-resistant steels for boiler tubes and pipes.
