GB/T 24593 Welded Austenitic Stainless Steel Tube For Heat Exchanger
Material Specification
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.
Key Features
- Corrosion Resistance: The austenitic stainless steel composition provides excellent resistance to corrosion, making it suitable for harsh environments.
- High Temperature Performance: These tubes can maintain their mechanical properties even at elevated temperatures.
- Weldability: The material is easily weldable, allowing for efficient fabrication and installation.
- Durability: Offers long service life due to its robust material properties.
Chemical Composition
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 |
Mechanical Properties
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 |
Steel Grade
The standard covers several steel grades, each with specific properties tailored for different applications. Common grades include:
- 304/304L: Known for its excellent corrosion resistance and formability.
- 316/316L: Offers enhanced resistance to pitting and crevice corrosion due to the presence of molybdenum.
- 321: Stabilized with titanium for improved resistance to intergranular corrosion.
Application
GB/T 24593 welded austenitic stainless steel tubes are primarily used in:
- Heat Exchangers: For efficient heat transfer in chemical processing and power plants.
- Petrochemical Industry: In equipment that requires resistance to high temperatures and corrosive substances.
- Food and Beverage Industry: Due to their non-reactive nature and ease of cleaning.
Possible Alternative Grades
While GB/T 24593 specifies certain grades, alternative materials may be considered depending on specific requirements:
- Duplex Stainless Steels: For applications requiring higher strength and corrosion resistance.
- Nickel Alloys: For extreme environments where standard stainless steels may not suffice.
- Titanium Alloys: When weight savings and superior corrosion resistance are critical.
