ASTM A213 T22,Alloy Steel Seamless Tube,Boiler,Superheater,Heat Exchanger

Overview

ASTM A213 is a standard specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. It covers a range of steel grades including T2, T5, T9, T11, T12, T22, T91, and T92, among others.ASTM A213 T22 specifically refers to a seamless ferritic alloy-steel tube with the composition suitable for high-temperature service. T22 is commonly used in power generation and petrochemical industries, particularly in boiler applications.The specification covers various mechanical properties such as tensile strength, yield strength, elongation, and hardness requirements. It also specifies the chemical composition of the steel, including elements like chromium, molybdenum, and carbon.
