ASTM A335 P91 is a standard specification for seamless ferritic alloy-steel pipes designed for high-temperature service. P91 is a chromium-molybdenum alloy steel with added vanadium and niobium, which provides excellent high-temperature strength, oxidation resistance, and creep resistance. It is widely used in power plants, petrochemical industries, and other high-temperature applications.
