ASTM A312 TP304H Stainless Steel Pipe With SS Fin Strip, Serrated Fin Tube For Furnace
Product Overview
ASTM A312 TP304H serrated fin tube is manufactured from high-temperature stainless steel pipe with stainless steel fin strips mechanically or resistance-welded onto the tube surface. The serrated fins improve heat transfer by disrupting the boundary layer of gas flow, making them ideal for high-temperature furnace and heater applications.

| P (Phosphorus) | ≤ 0.045 |
| S (Sulfur) | ≤ 0.030 |
| Cr (Chromium) | 18.00 – 20.00 |
| Ni (Nickel) | 8.00 – 11.00 |
| N (Nitrogen) | ≤ 0.10 |
| Fe (Iron) | Balance |
Mechanical Properties (ASTM A312 TP304H)
| Property | Value |
|---|---|
| Tensile Strength (MPa) | ≥ 515 |
| Yield Strength (MPa) | ≥ 205 |
| Elongation (%) | ≥ 35 |
| Hardness (HB) | ≤ 192 |
| Impact Toughness (J) | Good at high temp |
Applications
