Experiences in manufacturing of forgings for power generation application

Sufficient available energy is the precondition for a high standard of living in each country. This fact calls forthe need of an appropriate number of power generation plants with improved technologies to achieve higherefficiency combined with reduced environmental pollution – a challenge, which is not only aimed to the powerstation manufacturers but also to the producer of forgings who have to manufacture components from moreand more higher alloyed materials and for this reason more complex manufacturing processes.This paper reports about experiences in the fabrication of forged components for gas and steam turbineapplication up to achieved mechanical properties and NDT results, focused on the newer materialswith improved high temperature capability, and here the steels of the 9-12% Cr class developed in the frameof the European Cost research programme
