Cast heat-resistant austenitic steel with improved temperature creep properties and balanced alloying element additions and methodology for development of the same
Patent
·
OSTI ID:1080301
The present invention addresses the need for new austenitic steel compositions with higher creep strength and higher upper temperatures. The new austenitic steel compositions retain desirable phases, such as austenite, M.sub.23C.sub.6, and MC in its microstructure to higher temperatures. The present invention also discloses a methodology for the development of new austenitic steel compositions with higher creep strength and higher upper temperatures.
