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% |

The ASTM A498 specification includes several grades, each designed to meet specific performance criteria. The grades are differentiated based on their chemical composition and mechanical properties, allowing for tailored solutions in various industrial applications.
ASTM A498 stainless steel finned tubes are widely used in:
While ASTM A498 provides a robust solution for many applications, alternative grades may be considered depending on specific requirements:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
