A European project (COST 522) aims to improve power plant efficiency by developing stronger steel for steam turbines. These turbines operate with extremely hot steam (up to 650°C) to maximize efficiency and minimize emissions. The project focuses on ferritic-martensitic steel, which is suitable for the thick components used in these high-temperature environments. Building on prior advancements, COST 522 explored new steel formulations and tested them thoroughly. This has resulted in steels capable of withstanding even hotter steam (610°C live steam and 630°C reheat steam), paving the way for the next generation of highly efficient power plants.
