THE APPLICATION OF 9%Cr CASTING STEEL WITH Co AND B ADDITION FOR 620℃ STEAM TURBINE

摘要：

　　New 9%Cr cast steel with Co and B addition has been developed for 620℃ turbine application.Full size valve casting was trial manufactured and material properties were investigated by chemical analysis,microstructure analysis,room and elevated temperature tensile tests,and creep rupture tests.Evaluation results currently show the good performance for this potential using.
