ASME SA213 / ASTM A213 T2 / 15CrMo Alloy Steel Tube Seamless Heat Exchanger Tube
ASTM A213 Grade T2 Alloy Steel Seamless Tube is a standardized, chromium-molybdenum (Cr-Mo) low-alloy steel tubular product manufactured without a welded seam, specifically produced to meet the dimensional, mechanical, and metallurgical requirements of the ASTM A213 specification. When designated as a Heat Exchanger Tube, it is intended for use in high-temperature, high-pressure thermal transfer equipment such as shell-and-tube heat exchangers, condensers, and boilers, where resistance to creep, oxidation, and thermal fatigue is essential.
Why choose ally T2? T5, T9, and T22 are much more hardenable. T5/T9 are air-hardening (martensitic), requiring strict preheat (200–300°C) and immediate, precise PWHT. Choosing T2 saves significant fabrication time, lowers labor costs, and reduces the risk of welding defects (cracking) during shop assembly.

Comparasion among "T" series Alloy Steels
| Grade | Key Chemistry | Creep / High-Temp Strength | Oxidation Resistance | Weldability / Fabrication | Typical Max Service Temp | Primary Application |
| T1 | 0.5% Mo (no Cr) | Lowest among Cr-Mo grades | Poor (no Cr) | Excellent (no hardening issues) | ~480°C | Low-cost, mild elevated temp; largely obsolete. |
| T2 | 0.5% Cr – 0.5% Mo | Baseline / Moderate | Moderate | Good (preheat optional, easy PWHT) | ~540°C | General heat exchangers, moderate refinery duty. |
| T11 | 1.25% Cr – 0.5% Mo | Slightly higher than T2 | Better than T2 | Similar to T2 (good) | ~565°C | Feedwater heaters, higher-temp exchangers. |
| T22 | 2.25% Cr – 1.0% Mo | Significantly higher (2x creep strength vs T2) | Good | Fair (requires mandatory preheat & PWHT) | ~580°C | Boiler superheaters, severe power plant duty. |
| T5 | 5.0% Cr – 0.5% Mo | Similar to T2 | Excellent (high Cr) | Poor (air-hardening, difficult, strict PWHT) | ~650°C | Refinery furnace tubes, high sulfidation/oxidation. |
| T9 | 9.0% Cr – 1.0% Mo | Higher than T22 | Excellent (very high Cr) | Poor (martensitic, very strict handling) | ~650°C | Severe corrosion/oxidation, petrochemical crackers. |
| T91 | 9.0% Cr – 1.0% Mo – V/Nb | Highest (far exceeds all above) | Excellent | Moderate (requires careful PWHT) | ~650°C+ | Advanced ultra-supercritical power boilers. |
