Product Description
16Mo3 High Temperature Boiler Tube
16Mo3 is a low-alloy steel primarily used for pressure vessels and boilers operating at elevated temperatures. This material is standardized in EN 10028-2 (flat products for pressure purposes) and EN 10216-2 / EN 10217-2 (seamless and welded tubes).
Chemical Composition
| Element | Composition Range (Weight %) |
|---|---|
| Carbon (C) | 0.12 – 0.20 |
| Silicon (Si) | ≤ 0.35 |
| Manganese (Mn) | 0.40 – 0.90 |
| Phosphorus (P) | ≤ 0.025 |
| Sulfur (S) | ≤ 0.010 |
| Chromium (Cr) | ≤ 0.30 |
| Nickel (Ni) | ≤ 0.30 |
| Molybdenum (Mo) | 0.25 – 0.35 |
| Copper (Cu) | ≤ 0.30 |
| Nitrogen (N) | ≤ 0.012 |
| Aluminum (Al) | ≥ 0.020 (as total Al, for deoxidation) |
Key Composition Benefits
Molybdenum (0.25–0.35%)
- Increases high-temperature strength (creep resistance)
- Improves resistance to softening at elevated temperatures
- Provides better resistance to hydrogen attack and corrosion in boiler/pressure environments
Low Carbon + Controlled Manganese
Low carbon maintains good weldability and reduces brittle weld risk, while manganese enhances strength and toughness without compromising weldability.
Low Phosphorus & Sulfur
Minimized levels improve toughness, reduce hot cracking, and ensure better performance under pressure and high temperatures.
Controlled Chromium & Nickel
Present only as residuals; 16Mo3 offers better corrosion resistance than plain carbon steel but remains cost-effective compared to stainless steels.
Performance Characteristics
16Mo3 is selected for its optimal balance of properties including:
- Excellent weldability
- Adequate strength up to 500–530°C (depending on design code)
- Superior creep resistance compared to plain carbon steels like P235GH or P265GH
- Cost-effectiveness compared to Cr-Mo or stainless steels
Common Applications
16Mo3 is commonly specified for critical components in various industrial settings:
- Boiler tubes and heat exchanger tubes
- Steam lines and collector pipes
- Pressure vessels and headers in power plants
- Refinery and chemical plant equipment
