GB/T 24593 is a Chinese standard that specifies the requirements for welded austenitic stainless steel tubes used in heat exchangers. These tubes are designed to withstand high temperatures and corrosive environments, making them ideal for use in various industrial applications, including chemical processing, power generation, and oil refining.
The chemical composition of the welded austenitic stainless steel tubes under GB/T 24593 is crucial for ensuring their performance in heat exchangers. Below is a typical composition table:
| Element | Composition (%) |
|---|---|
| Carbon (C) | ≤ 0.08 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Chromium (Cr) | 18.00 - 20.00 |
| Nickel (Ni) | 8.00 - 11.00 |
| Molybdenum (Mo) | ≤ 0.75 |
The mechanical properties of these tubes are designed to ensure they can withstand the operational stresses encountered in heat exchangers. Below is a typical mechanical properties table:
| Property | Value |
|---|---|
| Tensile Strength (MPa) | ≥ 515 |
| Yield Strength (MPa) | ≥ 205 |
| Elongation (%) | ≥ 35 |
| Hardness (HRB) | ≤ 90 |
The standard covers several steel grades, each with specific properties tailored for different applications. Common grades include:
GB/T 24593 welded austenitic stainless steel tubes are primarily used in:
While GB/T 24593 specifies certain grades, alternative materials 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.
