oxidation and carburization in high-temperature atmospheres. It also
resists corrosion by many aqueous environments. The alloy maintains
a stable, austenitic structure during prolonged exposure to high
temperatures. Used for process piping, heat exchangers, carburizing
equipment, heating-element sheathing, and nuclear steam-generator
tubing.
