ASME SA213 T11 Seamless Alloy Tube 1.25Cr-0.5Mo Chrome Moly for Boiler Superheater Power Plant
| Chemical Composition | ||
| Element | Content Range (%) | Metallurgical Function |
| C (Carbon) | 0.05 – 0.15 | Ensures high-temperature strength and creep limit; upper limit controlled to maintain weldability |
| Si (Silicon) | 0.50 – 1.00 | Deoxidation; improves high-temperature oxidation resistance |
| Mn (Manganese) | 0.30 – 0.60 | Strengthens matrix; improves hot workability |
| P (Phosphorus) | ≤ 0.025 | Strictly controlled to minimize embrittlement |
| S (Sulfur) | ≤ 0.025 | Reduces hot cracking risk |
| Cr (Chromium) | 1.00 – 1.50 | Forms Cr₂O₃ protective scale for oxidation resistance up to 550°C; synergizes with Mo to enhance hot strength |
| Mo (Molybdenum) | 0.44 – 0.65 | Solid-solution strengthening; inhibits temper embrittlement; significantly improves creep resistance |
| Mechanical Properties | ||
| Parameter | Standard Requirement (Min.) | Typical Value |
| Tensile Strength (Rm) | ≥ 415 MPa | 460 – 580 MPa |
| Yield Strength (Rp0.2) | ≥ 205 MPa | 275 – 360 MPa |
| Elongation (50mm gage length) | ≥ 30% | 35% – 40% |
