| Element | Content Range (%) | Key Function |
|---|---|---|
| Nickel (Ni) | 30.0 - 35.0 | Maintains austenitic matrix stability; prevents embrittlement at high temperatures |
| Chromium (Cr) | 19.0 - 23.0 | Forms dense CrO oxide film; resists oxidation and high-temperature corrosion |
| Iron (Fe) | Balance | Reduces material cost while preserving processability |
| Carbon (C) | 0.05 - 0.10 | Enhances creep and rupture strength via carbide formation |
| Aluminum (Al) | 0.15 - 0.60 | Forms γ' strengthening phase with titanium; boosts high-temperature hardness |
| Titanium (Ti) | 0.15 - 0.60 | Works with Al to reinforce microstructure |
| Manganese (Mn) | ≤1.50 | Acts as deoxidizer; minimizes residual impurities |
| Sulfur (S) | ≤0.015 | Strictly controlled to avoid hot working defects |
| Phosphorus (P) | ≤0.030 | Limited to prevent brittleness in high-temperature service |
| Performance Metric | Room Temperature (Min.) | At 800°C (Min.) |
|---|---|---|
| Tensile Strength (Rm) | 450 MPa | 200 MPa |
| Yield Strength (Rp0.2) | 180 MPa | 100 MPa |
| Elongation (A5) | 35% | 25% |
| Density | 7.9 g/cm³ | 7.8 g/cm³ |
| Melting Point | 1300 - 1350°C | - |
| Feature | Hot Rolled Bars | Forged Bars |
|---|---|---|
| Processing Method | Continuous rolling at 1100-1200°C | Precision forging with controlled plastic deformation |
| Surface Finish | Black oxide scale (can be lightly ground) | Smooth, often turned/ground; minimal surface defects |
| Dimensional Tolerance | ±0.5mm | ±0.2mm |
| Microstructure | Coarse but uniform austenitic grains | Refined grain structure; eliminated internal porosity |
| Key Advantages | Cost-effective; efficient for standard applications | Superior creep resistance; uniform transverse/longitudinal strength |
| Ideal Applications | Flanges, valves, non-critical shafts | High-pressure turbine components, nuclear reactor parts |
