HF Welding Solid Fin Tubes ASTM A312 TP304H For Waste Heat Recovery Units
ASTM A312 is a standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes.
Chemical Composition (%)
| Grade | C | Mn | P | S | Si | Cr |
| TP304H | 0.04-0.10 | 2.00 | 0.045 | 0.030 | 1.00 | 18.00-20.00 |
Composition:
18-20% Chromium (Cr) – Provides oxidation resistance.
0.04-0.10% Carbon (C) – Improves creep resistance at high temps.
Mechanical Properties
| Grade | Tensile Strength,min | Yield Strength (0.2%Offset,min) |
| 75ksi (515 MPa) | 30ksi (205 MPa) | |
| TP304H | Elongation min. % | Heat Treating Temperature min. |
| 35% | 1900°F [1040°C] |
Corrosion Resistance: Excellent against oxidation, sulfur, and acidic flue gases.
Mechanical Strength: Good creep & stress rupture resistance (superior to standard 304).
Waste Heat Recovery Units (WHRUs) capture and reuse thermal energy from industrial exhaust gases, improving energy efficiency and reducing emissions. HF-welded solid fin tubes made of ASTM A312 TP304H stainless steel play a critical role in these systems due to their high-temperature strength, corrosion resistance, and efficient heat transfer capabilities.
304H stainless steel maintains strength at high temperatures (up to 900°C), ensuring long-term performance.Solid fins provide a larger heat exchange surface area than bare tubes, increasing thermal efficiency.
Applications in WHRU Systems
Heat Recovery Steam Generators (HRSGs)
Economizers
Air Preheaters
Flue Gas Condensers
HF-welded solid fin tubes (ASTM A312 TP304H) are essential for efficient, durable WHRUs in industries such as:Power generation (HRSGs, economizers) / Petrochemical (fired heaters, reformers) / Cement, steel, and waste incineration (flue gas heat recovery).
