Oxidation behavior of a commercial, cast Ni-base superalloy was studied in air-SO2 mixture, simulating combustion gases from high sulfur containing fuels. Experiments at 1050°C for up to 500 hours duration. The studied alloy was characterized with a number of analytical methods including SEM / EDX and GDOES after different oxidation times.
The T-8-20 Task Group conducted a survey of plant practices and of the performance of materials of constrution in HF Alkylation Units. A Primary goal of the survey was to expand the limited body of the information on alternative ally performance in HF Alkylation units and to better define the susceptibility of steel to hydrogen induced cracking.
