ASTM A213 T9 Alloy Steel Fin Tube, Studded Fin Tube for Furnace
ASTM A213 T9 Studded Fin Tube is a high-performance heat transfer component widely used in furnace and heater applications, particularly in convection zones. The tube body is made from T9 alloy steel, and carbon steel or alloy steel studs are resistance welded onto the tube’s surface in a uniform pattern. This design significantly enhances the heat transfer area and improves thermal efficiency in high-temperature and corrosive environments.

| Si | 0.25–1.00 |
| Cr | 8.00–10.00 |
| Mo | 0.90–1.10 |
| Fe | Balance |
| Property | Value |
|---|---|
| Tensile Strength | ≥ 415 MPa |
| Yield Strength | ≥ 205 MPa |
| Elongation | ≥ 30% |
| Max Operating Temp | ~ 600–650°C |
| Hardness | ≤ 192 HB |
Material: Carbon Steel / Alloy Steel
Attachment: Resistance welding
Spacing: Typically 10–15 mm apart in helical or parallel arrangement
Maximized Heat Transfer Area
The studs increase the outer surface area significantly, improving convective heat transfer efficiency, especially in gas-to-liquid or gas-to-gas applications.
High Temperature & Pressure Resistance
T9 alloy steel is specially formulated to endure high-temperature environments, making it suitable for furnace conditions up to 650°C.
Strong Weld Bonding
Studs are welded using resistance welding, ensuring strong adhesion and long service life under thermal cycling.
Ideal for Harsh Conditions
With excellent oxidation resistance and creep strength, studded fin tubes are ideal in sooty, dusty, or corrosive environments.
Easy Maintenance
The wide stud spacing makes it easier for soot blowers or manual cleaning, ensuring consistent heat transfer performance.
