Tensile strength at room temp: min 415 MPa
Yield strength at room temp: min 205 MPa
Elongation: min 30%
Hardness: max around 179 HB
High-temperature properties: allowable stresses varying with temperature, creep rupture strength.

2. Versatility

Wide Range of Applications: ASTM A335 P9 serrated fin tubes are used in various industries, including power generation, petrochemical, refining, and heat recovery systems.
Customizable Design: The tubes can be customized in terms of base tube dimensions, fin height, fin density, and serration pattern to meet specific application requirements.

3. Cost-Effectiveness

Long Service Life: The durability and resistance to high-temperature degradation reduce the need for frequent replacements, lowering long-term costs.
Energy Efficiency: The enhanced heat transfer efficiency of serrated fin tubes can lead to energy savings in heat exchange systems.

4. Compliance with Industry Standards

ASTM and ASME Standards: ASTM A335 P9 tubes comply with industry standards such as ASTM A335 and ASME SA335, ensuring high quality and reliability.
Certifications: These tubes are often tested and certified for mechanical properties, hydrostatic performance, and non-destructive testing (NDT), providing assurance of their performance.

5. Improved Thermal Performance

Higher Heat Transfer Coefficients: The serrated fin design results in higher heat transfer coefficients compared to smooth or plain fin tubes.
Efficient Thermal Cycling: The tubes perform well under thermal cycling conditions, making them suitable for applications with fluctuating temperatures.
