Samples of alloy 800 H (UNS N08810) and alloy 617 (UNS N06617) were oxidized in a simulated process gas atmosphere. The principal elements of the gaseous environment were 50% H2O 35% H2 and 5% of CO2, CO, and CH4, respectively and a total pressure of 140 kPa. This gas in it state of thermodynamic equilibrium establishes oxygen partial pressures ranging from...
