Product Overview – ASTM A213 TP310H Seamless Tubes
ASTM A213 TP310H is the high carbon modification of grade 310 stainless steel. The increased carbon content improves creep strength and structural stability under prolonged exposure to elevated temperatures.
Containing approximately 25% chromium and 20% nickel, TP310H provides outstanding oxidation resistance while maintaining mechanical integrity in extreme thermal environments.
These seamless stainless steel tubes are manufactured using hot finished or cold drawn processes to ensure uniform microstructure, precise wall thickness, and high-pressure performance.
TP310H seamless tubes are widely specified for superheaters, reheaters, high-pressure boilers, radiant sections, and petrochemical heater coils.
Compared to TP310S, TP310H offers improved high-temperature strength in long-term service conditions.
