| Molybdenum (Mo) | 2.0–3.0 | Pitting resistance |
| Carbon (C) | ≤0.03 | Weldability enhancement |
| Manganese (Mn) | ≤2.0 | Strength optimization |
Mechanical Properties
- Tensile Strength: ≥485 MPa
- Yield Strength: ≥170 MPa
- Elongation: ≥40%
- Hardness: ≤217 HB (Brinell)
Integrated Design Capabilities
Customization: Lip profiles optimized for shell/tube-side connections (sizes: 2"–24" NB)
All designs include DWG/STEP files and ASME BPV Code compliance reports.
Applications in Heat Exchangers
| Component | Function |
|---|---|
| Shell/Tube Connections | Primary pressure boundary for fluid in/outlet (self-reinforced lip resists hoop stress). |
| Channel-to-Tubesheet Joint | Leak-tight sealing under thermal cycling (lip integrates with gasket surfaces). |
| Vent/Drain Nozzles | Compact reinforcement for auxiliary piping per API 663 Sec. 5.4. |
