| Applications: | fluid and gas transport, structure , boiler, heat exchanger, super heater |
| Element | Content Range (%) | Purpose |
|---|---|---|
| Chromium (Cr) | 17.0 – 19.0 | Enhances corrosion resistance and oxidation resistance at high temperatures. |
| Nickel (Ni) | 9.0 – 13.0 | Stabilizes the austenitic structure, improving ductility and toughness. |
| Niobium (Nb) | ≥ 5 × C (min) | Prevents carbide precipitation (sensitization), enhancing intergranular corrosion resistance. |
| Carbon (C) | 0.04 – 0.10 | The "H" designation indicates higher carbon content, boosting high-temperature strength. |
| Manganese (Mn) | ≤ 2.0 | Aids in deoxidation and improves hot workability. |
| Silicon (Si) | ≤ 1.0 | Enhances oxidation resistance and acts as a deoxidizer. |
| Phosphorus (P) | ≤ 0.045 | Controlled to minimize brittleness. |
| Sulfur (S) | ≤ 0.030 | Reduces hot cracking during welding when kept at low levels. |
| Property | Minimum Value | Testing Condition |
|---|---|---|
| Tensile Strength | 515 MPa (75,000 psi) | Room temperature |
| Yield Strength (0.2% offset) | 205 MPa (30,000 psi) | Room temperature |
| Elongation (in 50 mm) | 40% | After annealing |
| Hardness (HRB) | 95 (max) | Room temperature |
| Industry | Applications |
|---|---|
| Power Generation | Boiler tubes, superheaters, reheaters, and high-pressure steam pipelines. |
| Petrochemical | Refinery equipment, catalytic crackers, and high-temperature process piping. |
| Chemical Processing | Reactors, heat exchangers, and pipelines handling corrosive fluids. |
