ASTM A498 is a specification that covers seamless and welded carbon and alloy steel tubes with integral fins. These tubes are primarily used in heat exchangers, where efficient heat transfer is critical. The specification includes various grades, such as Grade 1, 3, 6, 7, and 8, each offering distinct properties suitable for different applications.
Below is a table presenting the typical chemical composition for the ASTM A498 stainless steel finned tubes:
| Element | Grade 1 | Grade 3 | Grade 6 | Grade 7 | Grade 8 |
|---|---|---|---|---|---|
| Carbon (C) | ≤ 0.30% | ≤ 0.30% | ≤ 0.30% | ≤ 0.30% | ≤ 0.30% |
| Manganese (Mn) | 0.29-1.06% | 0.29-1.06% | 0.29-1.06% | 0.29-1.06% | 0.29-1.06% |
| Phosphorus (P) | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% |
| Sulfur (S) | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% |
| Silicon (Si) | ≤ 0.40% | ≤ 0.40% | ≤ 0.40% | ≤ 0.40% | ≤ 0.40% |
| Chromium (Cr) | 16.0-18.0% | 16.0-18.0% | 16.0-18.0% | 16.0-18.0% | 16.0-18.0% |
| Nickel (Ni) | 8.0-10.5% | 8.0-10.5% | 8.0-10.5% | 8.0-10.5% | 8.0-10.5% |
