High-frequency welded finned tubes integrate A335 P9 chromium-molybdenum alloy base tubes with carbon steel (CS) fins. This synergy delivers exceptional heat transfer efficiency (up to 98% weld integrity) and resistance to thermal stress (operating range: -50°C to 580°C). Ideal for high-pressure, corrosive industrial applications.
Our high-frequency welding (HFW) ensures metallurgical bonding without filler metals:
| Component | A335 P9 Base Tube (%) | Carbon Steel Fins (%) |
|---|---|---|
| Carbon (C) | 0.15 max | 0.25–0.35 |
| Chromium (Cr) | 8.0–10.0 | ≤ 0.40 |
| Molybdenum (Mo) | 0.90–1.10 | ≤ 0.15 |
| Silicon (Si) | 0.50–1.00 | 0.15–0.35 |
| Manganese (Mn) | 0.30–0.60 | 0.60–1.20 |
| Sulfur (S) | 0.025 max | 0.04 max |
| Parameter | Base Tube (A335 P9) | Fins (CS) |
|---|---|---|
| Outer Diameter | ±0.20 mm | ±0.05 mm |
| Thickness | ±10% nominal | ±0.03 mm |
| Fin Height | N/A | ±0.15 mm |
| Fin Density | N/A | 150–400 fins/meter |
| Straightness | ≤1.5 mm/m length | ≤1.0 mm/m length |
