The need for high temperature materials is encountered in a wide variety of modem industries, such as in metallurgical, chemical, petrochemical, glass manufacture, heat treatment, waste incinerators, heat recovery, advanced energy conversion systems and others. Some of the technologies like thermal treatment and management of municipal and hazardous waste, fluidized bed combustion, integrated combined cycle power plants and integrated chemical plants, utilizing coal gasification process for feed stock, and the burning of low grade heavy fuels in refineries, all these, combined with demands for greater efficiency and meeting stringent environmental pollution laws, have created a need for alloys which are highly resistant to severe sulfidizing, carburizing and oxidizing high temperature type attack. However, all high temperature materials have certain limitations and the optimum choice is often a compromise between mechanical constraints as imposed by operating temperatures and corrosion constraints due to process environments. This paper describes the development of a new nickel based high chromium/high silicon alloy, alloy 45TM (UNS N06045). Optimization of this alloy during the development process and its corrosion resistance behavior under various environments such as oxidizing, carburizing, sulfidizing, coal gasification (H{sub 2}S/CO/CO{sub 2}/H{sub 2}O), waste incineration (SO{sub 2}/HCl), and fluidized bed combustion is presented and discussed.
