ASTM A213/ASME SA213
Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
ASTM A213 covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes.
ASTM A213 T9 Tube is made up of a low carbon alloy steel that is suitable for high heat and high pressure applications like the chemical, power generation, petroleum and oil and gas industrial applications. The ASTM A213 T9 Tube is also used in the water supply, metallurgy, construction and ship building applications which require strong material.
