Product Description
10CrMo5-5 High Pressure and Temperature Steam Pipelines
10CrMo5-5 is a low-alloy heat-resistant steel commonly used in high-temperature and high-pressure applications such as boiler tubes, steam lines, and pressure vessels. It belongs to the family of chromium-molybdenum steels and is standardized in EN 10216-2 (seamless steel tubes for pressure purposes).

| Manganese (Mn) | 0.40 – 0.90 |
| Phosphorus (P) | ≤ 0.025 |
| Sulfur (S) | ≤ 0.010 |
| Chromium (Cr) | 0.50 – 0.80 |
| Molybdenum (Mo) | 0.45 – 0.60 |
| Nitrogen (N) | ≤ 0.012 |
| Copper (Cu) | ≤ 0.30 |
| Nickel (Ni) | ≤ 0.30 |
| Iron (Fe) | Balance |
Element Functions
- C (Carbon): Controls strength and hardness; kept moderate to retain good weldability
- Cr (Chromium): Improves oxidation and corrosion resistance, and high-temperature strength
- Mo (Molybdenum): Increases creep resistance and strength at elevated temperatures
- Mn, Si: Aid deoxidation and contribute to strength and toughness
- P, S: Kept very low to avoid brittleness and weldability problems
Important Note: When designing or welding with 10CrMo5-5, always refer to the exact standard and mill certificate for your batch. Minor variations within the permitted range can affect properties and allowable stress calculations, especially in critical pressure equipment.
