Abstract
Cover Photo: Gas turbine of a 530 MW gas and steam power station, working at 3000 r.p.m. and 1500°C, resulting in an efficiency of 60%. This performance is enabled by heat resistant steels like 16Mo3, 27NiCrMoV15‐6 or X12CrMoWVNbN10‐1‐1. 2009 Steel Innovation Prize by the German Steel Industry Association.
