Abstract (en)
[origin: US2008149047A1] A steam boiler module or steam boiler assembly or a power station component is composed essentially of an alloyed, in particular chromium-containing material and consists, at least in part of a material which has been treated by surface blasting (shot-peening/shot blasting). With steam boilers having outlet temperatures of >=700° C. in power station components, in particular steam generator modules, the material provides an adequate strength, in particular long-term rupture strength and an adequate corrosion resistance as well as oxidation resistance. The material has a ferritic or martensitic or austenitic structure having a mean chromium content <=18% by weight, and at least a module surface or module group surface or component surface that has been treated, at least in part, by surface blasting (shot-peening/shot blasting).
