Material Overview: TP304H Stainless Steel
TP304H is a high-carbon variation of TP304 stainless steel, offering enhanced strength and thermal stability at elevated temperatures. It is commonly used in high-pressure and high-temperature heat recovery systems, such as HRSG applications. Below is a comparison of TP304, TP304L, and TP304H materials:
| Property | TP304 | TP304L | TP304H |
|---|---|---|---|
| Carbon (C) Content | ≤ 0.08% | ≤ 0.03% | 0.04% - 0.10% |
| High-Temperature Strength | Medium | Low | High |
| Corrosion Resistance | Excellent | Excellent | Excellent |
| Weldability | Excellent | Superior (low C content avoids sensitization) | Good |
| Applications | General-purpose | Low-corrosion environments | High-temperature systems |
Serrated Fin Tube Overview
Serrated (or segmented) fin tubes are designed to maximize heat transfer efficiency by increasing the surface area exposed to the working fluid. These fins are manufactured using High-Frequency Welding (HFW) technology, ensuring a robust bond between the fins and the base tube.
