ASME SA213 TP304H Stainless Steel Seamless Heat Exchanger Tube Bright Annealed
ASME SA213 is a standard issued by the American Society of Mechanical Engineers, specifically for seamless ferritic and austenitic alloy steel tubing used in boilers, superheaters, and heat exchangers. It specifies the material's chemical composition, mechanical properties, heat treatment requirements, and testing methods, serving as the fundamental basis for ensuring the safe and reliable operation of the tubing under high-temperature and high-pressure environments.
The "H" in TP304H indicates High Carbon, with a carbon content range (0.04-0.10%) higher than that of ordinary 304 (≤0.08%). The "H" type is specifically designed for high-temperature applications; the higher carbon content allows for the formation of more stable carbides at high temperatures, thus providing higher high-temperature strength (creep resistance).
