They generally include certain design features developed for markets and operating environments outside the US, where new coal-fired plants have been built in recent decades. US market conditions are different, and considerable capital cost savings with negligible operating cost differences are possible if technology options are considered for the next wave of supercritical and ultra-supercritical steam plants. 8 figs.

As temperatures increase, the ferritic materials presently being used in fossil boilers will not possess adequate steamside oxidation corrosion resistance. Ultrasupercritical boilers are being developed to operate with steam temperatures up to 760°C (1400°F), so new ferritic and austenitic materials must be utilized that possess excellent steamside oxidation resistance while meeting the required mechanical properties.
