Abstract
Bei einem Dampferzeugerbauteil oder -baugruppe oder einer Kraftwerkskomponente, das/die zumindest im Wesentlichen aus einem legierten, insbesondere chromhaltigen, Werkstoff besteht und zumindest zum Teil, insbesondere im Wesentlichen, aus einem Werkstoff besteht, der mittels Oberflächenstrahlen (shot-peening/shot-blasting) behandelt ist, soll eine Lösung geschaffen werden, mit welcher Materialien zur Verfügung gestellt werden, die bei Dampferzeugern mit Austrittstemperaturen von ≥ 700 °C in Kraftwerkskomponenten, insbesondere Dampferzeugerbauteilen, eine ausreichende Festigkeit, insbesondere Zeitstandfestigkeit, und eine ausreichende Korrosionsbeständigkeit sowie Oxidationsbeständigkeit aufweisen. Dies wird dadurch erreicht, dass es/sie zumindest im Wesentlichen aus einem Werkstoff mit ferritischem oder martensitischem oder austenitischem Gefüge mit einem mittleren Chromgehalt von < 18 Gew.-% besteht und zumindest eine Bauteils- oder Baugruppenfläche oder Komponentenfläche zumindest teilweise mittels Oberflächenstrahlen (shot-peening/shot-blasting) behandelt ist.In a steam generator component or assembly or a power plant component, which / consists at least substantially of an alloyed, in particular chromium-containing, material and at least partially, in particular substantially, consists of a material by means of surface blasting (shot-peening / shot-blasting ), a solution is to be provided with which materials are made available which have steam generators with outlet temperatures of ≥ 700 ° C in power plant components, in particular steam generator components, sufficient strength, especially creep rupture strength, and sufficient corrosion resistance and oxidation resistance. This is achieved in that it / at least substantially consists of a material with a ferritic or martensitic or austenitic structure with an average chromium content of < 18% by weight and at least one component or assembly surface or component surface at least partially by means of surface blasting (shot blasting). peening / shot-blasting).
