“Austenitic stainless steels (300 Series) are generally used for oxidation resistance up to about 1500°F (815°C). At higher temperatures, scaling and loss of protective chromium oxide layers increase.”
“Above these temperatures, specialized high-temperature alloys may be required.”
(Reference: API RP 571, Section 5.1.1 – Oxidation)
Therefore, option C is the correct answer.
