ASTM A312 TP347H is a high-temperature, stabilized austenitic stainless steel with added columbium (niobium) for improved creep strength. When made into Serrated Fin Tubes using High-Frequency Welding (HFW), this tube becomes ideal for furnace convection sections, offering enhanced heat transfer efficiency and extended service life under cyclic thermal stress and oxidizing conditions.

High Temperature Resistance
Ideal for superheaters, heaters, and furnaces, TP347H withstands long-term service at elevated temperatures without creep deformation.
Improved Heat Transfer Efficiency
The serrated fin design increases turbulence and surface area, boosting heat transfer while minimizing fouling.
Oxidation & Corrosion Resistance
Excellent performance in oxidizing atmospheres, especially in fuel-fired furnaces.
Creep-Strength Enhanced
Addition of niobium enhances structural stability under high stress and thermal cycling.
Weldability and Fabrication
Good weldability with standard procedures; suitable for custom-designed fin configurations.
The Serrated Fin Tube made of ASTM A312 TP347H is specifically used in:
Convection Section of Furnaces
Absorbs radiant heat and transfers it efficiently to the working fluid (steam, oil, or gas).
Heater Banks & Superheaters
Installed where both thermal efficiency and material durability are critical.
Refinery Fired Heaters
In hydrocarbon processing, TP347H fin tubes are used in crude, reformer, and hydrotreater furnaces.
