The GB/T 24590 standard specifies the requirements for enhanced alloy seamless tubes designed for use in efficient heat exchangers. These tubes are engineered to withstand high temperatures and pressures, making them ideal for demanding industrial applications. This article explores the material specifications, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades of these seamless tubes.
GB/T 24590 seamless tubes are manufactured from high-quality alloy steels. These materials are selected for their excellent thermal conductivity, corrosion resistance, and mechanical strength, ensuring optimal performance in heat exchanger applications.
The chemical composition of GB/T 24590 seamless tubes is critical to their performance. Below is a typical composition table:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.05 - 0.15 |
| Silicon (Si) | 0.20 - 0.50 |
| Manganese (Mn) | 0.30 - 0.80 |
| Phosphorus (P) | ≤ 0.030 |
| Sulfur (S) | ≤ 0.030 |
| Chromium (Cr) | 0.50 - 1.20 |
| Nickel (Ni) | 0.30 - 0.80 |
| Molybdenum (Mo) | 0.15 - 0.30 |
The mechanical properties of these tubes ensure they can handle the rigorous demands of heat exchanger applications. Below is a table of typical mechanical properties:
| Property | Value |
|---|---|
| Tensile Strength | 450 - 650 MPa |
| Yield Strength | ≥ 240 MPa |
| Elongation | ≥ 20% |
| Hardness | ≤ 200 HB |
The GB/T 24590 standard includes various steel grades, each tailored for specific applications. Common grades include:
GB/T 24590 seamless tubes are widely used in:
While GB/T 24590 tubes are highly effective, alternative grades may be considered based on specific requirements:
