The GB/T 24593 standard specifies the material requirements for welded austenitic stainless steel tubes used in boiler and heat exchanger applications. These tubes are manufactured using high-quality stainless steel, ensuring superior performance and longevity in demanding environments.
The key features of GB/T 24593 welded austenitic stainless steel tubes include:
Corrosion Resistance: Austenitic stainless steels have excellent corrosion resistance, making them suitable for use in high-temperature and corrosive environments encountered in boilers and heat exchangers.
High Temperature Strength: These stainless steel tubes exhibit exceptional mechanical strength at elevated temperatures, allowing them to withstand the rigorous conditions of boilers and heat exchangers.
Weldability: GB/T 24593 tubes are specifically designed for welding, providing ease and reliability during the fabrication process.
The following table presents the chemical composition requirements of GB/T 24593 welded austenitic stainless steel tubes:
| Grade | Chemical Composition (%) |
|---|---|
| Grade 304 | C ≤ 0.08, Si ≤ 1.00, Mn ≤ 2.00, P ≤ 0.045, S ≤ 0.030, Cr 18.0-20.0, Ni 8.0-10.5 |
| Grade 304L | C ≤ 0.035, Si ≤ 1.00, Mn ≤ 2.00, P ≤ 0.045, S ≤ 0.030, Cr 18.0-20.0, Ni 9.0-13.0 |
| Grade 316 | C ≤ 0.08, Si ≤ 1.00, Mn ≤ 2.00, P ≤ 0.045, S ≤ 0.030, Cr 16.0-18.0, Ni 10.0-14.0, Mo 2.0-3.0 |
| Grade 316L | C ≤ 0.035, Si ≤ 1.00, Mn ≤ 2.00, P ≤ 0.045, S ≤ 0.030, Cr 16.0-18.0, Ni 10.0-14.0, Mo 2.0-3.0 |
The mechanical properties of GB/T 24593 welded austenitic stainless steel tubes are as follows:
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|
| Grade 304 | ≥ 520 | ≥ 205 | ≥ 35 |
| Grade 304L | ≥ 480 | ≥ 175 | ≥ 35 |
| Grade 316 | ≥ 520 | ≥ 205 | ≥ 35 |
| Grade 316L | ≥ 480 | ≥ 175 | ≥ 35 |
The steel grades specified in GB/T 24593 include Grade 304, Grade 304L, Grade 316, and Grade 316L. These grades are commonly used in the manufacturing of boiler and heat exchanger tubes due to their excellent mechanical properties and corrosion resistance.
The application of GB/T 24593 welded austenitic stainless steel tubes encompasses a wide range of industries. Some common applications include:
Boiler Tubes: These tubes are extensively used in the construction of boilers to transfer heat from the combustion chamber to the water, generating steam for industrial processes.
Heat Exchanger Tubes: GB/T 24593 tubes are employed in heat exchangers to transfer heat between two fluids, enabling efficient energy exchange in various industrial processes.
Power Generation: Stainless steel tubes specified in GB/T 24593 are widely utilized in power plants for steam generation and heat exchange processes.
Chemical and Petrochemical Industries: GB/T 24593 tubes find applications in chemical and petrochemical plants, where resistance to corrosion and high temperatures is crucial.
While GB/T 24593 specifies Grade 304, Grade 304L, Grade 316, and Grade 316L stainless steel tubes for boiler and heat exchanger applications, alternative grades for specific requirements may be considered. Some possible alternative grades include:
Grade 321: Distinguished by its enhanced resistance to intergranular corrosion, Grade 321 stainless steel is suitable for applications where extended exposure to high temperatures is expected.
Grade 310: This grade offers excellent resistance to oxidation at high temperatures and is often used in heat treatment equipment and thermal processing applications.
Super Duplex Stainless Steels: These alloys provide superior resistance to chloride-induced stress corrosion cracking and are ideal for highly corrosive environments encountered in the petrochemical and offshore industries.
