ASTM A213 T5 K41545 Seamless Chromium Molybdenum Alloy Steel Tube For Heat Exchanger Equipment
ASTM A213 T5 K41545 Seamless Chromium Molybdenum Alloy Steel Tube For Heat Exchanger Equipment
ASTM A213 T5 (UNS K41545) is a seamless alloy steel tube optimized for high-temperature service, offering a balance of strength, oxidation resistance, and manufacturability. Its primary use in power and petrochemical industries underscores its reliability in demanding thermal environments. ASME SA213 T5 Alloy Steel Tubes are usually used in High-temperature and high-pressure environments, such as Boilers, superheaters, heat exchangers and some other Industries, like Power generation, petrochemical, refineries. This chromium molybdenum alloy steel seamless tubes have good temperature resistance, which is effective up to ~600°C (1112°F).
Key Advantages:
- Seamless Construction: Superior for high-pressure applications compared to welded tubes.
- Oxidation Resistance: Chromium content resists scaling at elevated temperatures.
- Creep Strength: Molybdenum enhances long-term stress resistance under heat.
Chemical Compositions:
| C, % | Mn, % | P, % | S, % | Si, % | Cr, % | Mo, % |
| 0.15 max | 0.30-0.60 | 0.025 max | 0.025 max | 0.50 max | 4.00-6.00 | 0.45-0.65 |
Mechanical Properties:
| Grade | Tensile Strength(MPa) | Yield Strength(MPa) | Elongation(%) | Hardness(HB) |
| A213 T5 | ≥415 | ≥205 | 30 | ≤163 |
Comparison with Other Grades:
- T5 vs T9/T11/T22: Lower chromium than T9 (9Cr-1Mo) and T22 (2.25Cr-1Mo), making it a mid-range option for thermal applications.
- Corrosion Resistance: Better than carbon steel but inferior to stainless steels; often used in non-corrosive, high-temperature settings.
