摘要：
The E911 steel grade has been developed from grade P91 to increase the creep properties at 600 degreesC through the control of vanadium, nitrogen and the addition of tungsten, Grade 911 shows a better creep performance than grade 91, Microstructure stability of both steels was investigated by isothermal ageing tests for up to 10,000 hours at 600 and 650 degreesC and their mechanical behaviour is compared, Results on welded joints have also been compared with base material.
