Extensive database of long term, high temperature test results.
High room and elevated temperature strength.Good creep.
High notch tolerance.
The alloy is usually produced by EAF /VD /LF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
