Product Description
ASME SA213 T11 Seamless Alloy Tube 1.25Cr-0.5Mo Chrome Moly for Boiler Superheater Power Plant
ASME SA213 T11 corresponds to ASTM A213 T11. It is a low-alloy chromium-molybdenum steel seamless pipe, belonging to the category of ferritic heat-resistant steel. This material is manufactured according to ASME SA213 / ASTM A213 standards and is specifically designed for high-temperature pressure equipment such as boilers, superheaters, and heat exchangers.
SA213 T11 is suitable for medium- and high-pressure boilers and high-temperature pipelines in petrochemical industries with metal operating temperatures ≤ 550°C. Through the alloying design of chromium and molybdenum, it exhibits excellent heat resistance, oxidation resistance, and good weldability below 550°C.
| 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% |
| Hardness | ≤ 163 HBW / ≤ 85 HRB | 140 – 160 HBW |
| High-Temperature Yield Strength (550°C) | — | Approx. 205 MPa |
| Physical Properties (Reference Values) | ||
| Parameter | Value | Unit |
| Density | ~7.85 | g/cm³ |
| Elastic Modulus (20°C) | ~210 | GPa |
| Thermal Conductivity | ~42 | W/(m·K) |
| Coefficient of Linear Expansion (20–400°C) | ~12.5 | ×10⁻⁶/°C |
