Product Description
13CrMo4-5 Steam Superheaters Pipes
13CrMo4-5 is a low-alloy heat-resistant steel widely used in pressure vessels, boilers, and high-temperature piping systems, particularly in power plants and petrochemical facilities. Its chemical composition is standardized in EN 10028-2 and EN 10216-2.
Chemical Composition
| Element | Content (Weight %) |
|---|---|
| Carbon (C) | 0.10 – 0.18 |
| Silicon (Si) | ≤ 0.35 |
| Manganese (Mn) | 0.40 – 0.70 |
| Phosphorus (P) | ≤ 0.025 |
| Sulfur (S) | ≤ 0.010 |
| Chromium (Cr) | 0.70 – 1.15 |
| Molybdenum (Mo) | 0.40 – 0.60 |
| Nitrogen (N) | ≤ 0.012 |
| Copper (Cu) | ≤ 0.30 |
| Nickel (Ni) | ≤ 0.30 |
Composition Benefits
- Chromium (approx. 1%): Enhances oxidation and corrosion resistance at elevated temperatures while maintaining strength and microstructural stability during long-term service
- Molybdenum (approx. 0.5%): Increases creep strength and enhances high-temperature tensile performance
- Medium Carbon and Manganese: Provides optimal balance of strength, toughness, and weldability
- Low Phosphorus and Sulfur: Controlled levels improve toughness and reduce risks of hot cracking and embrittlement
Typical Applications
- Boiler drums, headers, and steam lines
- High-temperature pressure vessels
- Superheater and reheater tubes
- Power plant and refinery components operating at 450–550°C
Important Note: For design, material selection, or welding procedure qualification, always refer to the actual standards (EN 10028-2, EN 10216-2) or mill test certificates for exact specified limits and measured composition values.
