ASME SA213 T5 Alloy Steel Tube Seamless Hot Rolled for Boiler and Heat Exchanger Application
ASTM A213 is a standard for seamless ferritic/austenitic alloy steel tubes for boilers, superheaters, and heat exchangers, and T5 is the specific material grade under this standard. T5 belongs to medium chromium molybdenum alloy steel, which has high temperature oxidation resistance and creep resistance, and is suitable for high-pressure and high-temperature environments.
