Extruded Finned Tube ASME SA249 TP304 with AL1060 Fins For Heat Exchanger and Boiler
The Extruded Finned Tube ASME SA249 TP304 with AL1060 Fins is a specialized type of heat transfer tube designed for use in heat exchangers and boilers. It combines the corrosion resistance and strength of stainless steel (TP304) with the excellent thermal conductivity of aluminum fins (AL1060). This combination makes it highly efficient for heat transfer applications in demanding environments.
Here’s a detailed breakdown of its components and applications:
1. Components of the Extruded Finned Tube
TP304 is a grade of austenitic stainless steel known for its excellent corrosion resistance, high-temperature strength, and durability.
It is suitable for use in corrosive environments, high-temperature applications, and processes requiring hygienic conditions (e.g., food and beverage, pharmaceuticals).
The base tube is manufactured according to the ASME SA249 standard, which specifies seamless stainless steel tubes for boilers, superheaters, and heat exchangers.
AL1060 is a commercially pure aluminum alloy (99.6% aluminum) with excellent thermal conductivity, lightweight properties, and good corrosion resistance.
The fins are extruded onto the base tube, creating a strong mechanical bond between the aluminum fins and the stainless steel tube. This ensures efficient heat transfer and durability.
The fins are formed by extruding aluminum through a die, which creates a seamless and tightly bonded fin structure around the stainless steel tube.
This design maximizes the surface area for heat transfer, improving the overall efficiency of the heat exchanger or boiler.

4. Chemical Composition of ASTM A249 TP304
The chemical composition of TP304 stainless steel is defined by the ASTM A249 standard. Here are the typical values:
| Element | Composition (%) |
| Carbon (C) | ≤ 0.08 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Silicon (Si) | ≤ 1.00 |
| Chromium (Cr) | 18.00–20.00 |
| Nickel (Ni) | 8.00–11.00 |
| Iron (Fe) | Balance |
5. Mechanical Properties of ASTM A249 TP304
The mechanical properties of TP304 stainless steel are also specified by the ASTM A249 standard. These properties are typically measured at room temperature.
| Property | Value |
| Tensile Strength | ≥ 515 MPa (75,000 psi) |
| Yield Strength (0.2% Offset) | ≥ 205 MPa (30,000 psi) |
| Elongation (in 2 inches) | ≥ 35% |
| Hardness (Rockwell B) | ≤ 90 HRB |
