| High Light | ASME SA213 T22 seamless alloy steel tubes ，seamless steel tubes for boilers ，alloy steel tubes for heat exchangers | ||
These are ASME SA213 (equivalently ASTM A213) seamless alloy steel tubes—commonly referred to as Chrome‑Moly tubes—specifically in grades T11, T12, and T22. They are fabricated to deliver high-performance characteristics in elevated temperature environments, making them ideal for boilers, superheaters, and heat exchangers.
Below is the chemical composition (in weight %) for T11, T12, and T22, per the ASME SA213 / ASTM A213 specification:
| Grade | C | Mn | P | S | Si | Cr | Mo |
|---|---|---|---|---|---|---|---|
| T11 | 0.05–0.15 | 0.30–0.60 | ≤ 0.025 | ≤ 0.035 | 0.50–1.00 | 1.00–1.50 | 0.44–0.65 |
| T12 | 0.05–0.15 | 0.30–0.61 | ≤ 0.025 | ≤ 0.035 | 0.5 | 0.80–1.25 | 0.44–0.65 |
| T22 | 0.05–0.15 | 0.30–0.60 | ≤ 0.025 | ≤ 0.035 | 0.5 | 1.90–2.60 | 0.87–1.13 |
Here are the key mechanical properties as per the standard (tensile strength, yield strength, elongation, hardness):
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HRB) |
|---|---|---|---|---|
| T11 | ≥ 415 | ≥ 220 | ≥ 30 | ≤ 85 |
| T12 | ≥ 415 | ≥ 220 | ≥ 30 | ≤ 85 |
| T22 | ≥ 415 | ≥ 220 | ≥ 30 | ≤ 85 |
Although you requested five similar grades, this particular standard only covers T11, T12, and T22. However, for context, other A213/SA213 alloy grades include T2, T5, T9, T91, T92—used in comparable high-temperature boiler and heat exchanger applications, though not part of your core grades.
Outstanding high-temperature strength: Chromium and molybdenum content helps retain mechanical stability and resist creep at elevated temperatures.
Corrosion and oxidation resistance: Ideal for harsh thermal environments, such as superheaters and steam cycles.
Excellent thermal conductivity: Supports efficient heat transfer in thermal systems.
Good weldability and formability: Suitable for fabrication, welding, and installation into complex assemblies.
Durability and longevity: Maintains performance through cycles of high pressure and temperature.
ASME SA213 / ASTM A213 – for seamless ferritic and austenitic alloy steel tubing for boilers, superheaters, and heat exchangers.
ASTM A1016/A1016M – General requirements for ferritic and alloy steel tubes referenced by ASME SA213.
