Abstract

The carburization behavior of 310 stainless steel has been studied after cyclic exposures to carburizing gas mixtures at elevated temperatures for 500 hr exposures. A thermodynamic analysis indicated that 1000°C was an approximate critical temperature, below which the environment should result in mixed oxidizing/carburizing behavior while above this temperature, reducing-carburizing behavior should occur. The experimental results agree well with the thermodynamic analysis, at 800°C in 2% CH₄/H₂ for 310SS which suffers both external oxidation, carburization, and internal carburization. At 1100°C in 10% CH₄/H₂ external carburization occurs and internal carburization becomes less pronounced. Schematics are illustrated to show corrosion mechanisms in various exposure environments.
