ASTM A213 TP348H is an austenitic stainless steel seamless tube manufactured under the ASTM A213 / ASME SA213 specification. This standard covers seamless ferritic and austenitic alloy steel tubes used in boilers, superheaters, and heat exchangers that operate in high-temperature and high-pressure environments.
ASTM A213 TP348H is a high-temperature version of the TP348 stainless steel grade and is specially designed for elevated-temperature service. The “H” designation indicates higher carbon content, which improves creep strength, stress-rupture resistance, and structural stability during prolonged exposure to high heat conditions in industrial systems.
