An increase in operating temperature and pressure of a steam turbine leads to an increase in system efficiency of the power plant. To meet the requirements of high flexibility at low costs, new ferritic steels of higher creep rupture strength are needed. Investigations have been performed for the production and processing of thick walled components in the hot steamline system. The tested materials were T 91/P 91, a new steel included in ASTM/ASME, and a W-modified 12% Cr-steel being under development. The mechanical test results on the various products were all in accordance with the ASTM specifications. An influence of bending on the mechanical properties has not been observed. Creep tests show that also the time-dependent strength values ...
