Creep strength of austenitic stainless steels for boiler applications
2014 (English)In: Coal Power Plant Materials and Life Assessment: Developments and Applications, Elsevier, 2014, 127-146 p.Chapter in book (Other academic)Text
For future ultra-supercritical power plants, creep-resistant austenitic stainless steel will play a most important role when steam temperatures are raised from 600°C to 700°C. To be economically viable, the 100 000. h creep rupture strength must be at least 100. MPa at the operating temperature. Also adequate corrosion resistance and manufacturing properties must be available. At 700°C the strength level has not yet been fully reached. In this chapter, the mechanisms controlling creep rupture properties of austenitic stainless steel are surveyed. Different possibilities to increase the strength are summarized. For future plants with a design life of 30. years or more, basic and quantitative modelling of the strength is crucial. How such models can be set up is reviewed.
