ASTM A335 P9 Alloy Steel Seamless Tube For High Temperature Service

Overview

ASTM A335 P9 is a specific grade of seamless ferritic alloy-steel pipe that is commonly used for high-temperature service. It is designed to withstand elevated temperatures and provide excellent creep and stress rupture strength. The "P" in the designation indicates that it is a pressure vessel grade， and the number "9" represents its chromium content.ASTM A335 P9 offers good resistance to oxidation， corrosion， and high-temperature creep. It is commonly used in power generation， petrochemical， and refinery applications where high-temperature and high-pressure conditions are present.
