ASTM A335 P9 is a chromium-molybdenum alloy steel (Cr-Mo) designed for high-temperature applications such as steam pipes, furnaces, and power generation systems.
This material provides excellent creep strength, oxidation resistance, and long-term durability in high-temperature environments, making it ideal for heat exchangers, boilers, and radiator tubes in systems where high thermal performance is essential.
The serrated fin design increases the surface area available for heat exchange and promotes turbulence in the fluid or gas passing over the tube, which improves heat transfer efficiency.
The serrated edges of the fins help reduce the boundary layer of fluid around the tube, improving heat dissipation and making it particularly effective in radiator tube applications.
The 13Cr (13% Chromium) stainless steel fins provide excellent corrosion resistance in high-temperature environments, making this tube ideal for use in heat exchangers and radiators exposed to hot gases, steam, and other corrosive environments.
13Cr stainless steel also offers good wear resistance and thermal stability, ensuring the fins retain their mechanical integrity under the stresses of thermal cycling and high-pressure conditions.
This HFW serrated fin tube is specifically designed for use in radiator tubes, furnaces, and heat exchangers, where efficient heat dissipation and thermal performance are essential in high-temperature applications.
The tube is ideal for cooling systems, furnaces, boilers, and power generation systems where maximizing heat transfer efficiency and minimizing space are key factors.
