ASTM A333 Gr.1 Low Fin Tube
ASTM A333 Gr.1 is a carbon steel grade specifically designed for low-temperature service. Its key characteristic is excellent impact toughness at sub-zero temperatures, making it suitable for applications where brittle fracture is a concern.
The ASTM A333 Gr.1 Low Fin Tube is an integrally finned tubular product manufactured by cold-forming fins from the wall of the base tube. This design significantly increases the external surface area, enhancing heat transfer efficiency while maintaining the material's inherent low-temperature toughness.

| Range | 0.30 max | 0.40-1.06 | 0.025 max | 0.025 max | 0.10-0.32 |
Mechanical Properties
| Tensile Strength | Yield Strength | Elongation | Impact Test Temperature |
| ≥ 380 MPa (55 ksi) | ≥ 205 MPa (30 ksi) | ≥ 35% | -45°C (-50°F) |
Key Features & Advantages
Low Temperature Toughness: Guaranteed impact properties at temperatures as low as -45°C (-50°F)
Enhanced Heat Transfer: Low fin design increases heat transfer area by approximately 2.5-3.5 times compared to bare tubes
Integral Fin Construction: Fins formed from the tube wall ensure perfect thermal contact and mechanical integrity
Cost-Effective Solution: More economical than stainless steels for low-temperature applications
Compact Design: Allows for smaller heat exchanger bundles while maintaining thermal performance
Comparison with Related Grades
Gr.1 vs. Gr.6:
Gr.6 contains 3.5% nickel for service at even lower temperatures (down to -100°C). Gr.1 serves as the economical choice for moderate low-temperature applications.
Applications of ASTM A333 Gr.1 Low Fin Tube
LNG Processing: Heat exchangers and vaporizers in liquefied natural gas facilities
Refrigeration Systems: Evaporators and condensers in industrial refrigeration
Chemical Processing: Low-temperature heat exchangers in petrochemical plants
Cryogenic Storage: Heat transfer equipment for liquid gases storage systems
Industrial Gas Plants: Heat exchangers in air separation and gas processing units
The ASTM A333 Gr.1 Low Fin Tube combines excellent low-temperature mechanical properties with enhanced heat transfer capability, making it an ideal choice for efficient and reliable performance in cryogenic and low-temperature heat exchange applications.
