摘要
为提高火电厂的效率对新的高铬钢性能进行了研究。其结果表明：铁素体－马氏体9%～12%铬钢可以用于蒸汽参数为300bar、610℃/625℃的火电机组，其热效率可达到48%左右。
For improving thermal efficiency, the mechanical properties of newly high chromium steels were tested and studied. Its results are showing: the ferritic-martensitic 9% to 12% Cr steels permit for the use of the units with steam parameter of 300bar、610℃/625℃. The thermal efficiency of these units will reach around 48%.
