... Abstract During a planned shut-down in 1990 it appeared that the bottom manifold parts made of wrought Incoloy 800H had undergone diametrical expansion of up to 2% due to creep. Further, cracking at the outer diam was found. It was decided to replace these parts. Microscopical investigations...

..., and Incoloy 800H, respectively. Visual examination of the bellows revealed cracks in heavily cold-worked areas (both inside and outside) and considerable corrosion. SEM analysis showed a classical intergranular failure pattern with microcracking. The threaded tie rod microstructure contained spheroidized...

.... Stress-relaxation cracking has been observed in the 300-series stainless steel alloys as well as higher Fe-Ni-Cr alloys such as alloy 800H and Inconel 617. The damage mechanism normally occurs between 500 and 750 °C (930 and 1380 °F), and susceptible materials typically fail within 1 or 2 years...
