ASTM A12 Stainless Steel TP304H HFW / High Frequency Welded Finned Tube for Heat Exchanger
YUHONG has been in business to supplying types of finned tubes for many years. We can supply embedded/extruded/wound/welding types in grade stainless steel, carbon steel, alloy steel, nickel alloy, copper alloy. In order to forward you a rapid quotation, please send inquiry with base tube details (Diameter, thickness, length, material) and fin details (material, fin type, height, thickness, spacing, finned length and unfinned sections).
304H Stainless Steel Pipes and Tubes Corrosion Resistance
Excellent in a wide range of atmospheric environments and many
corrosive media. Subject to pitting and crevice corrosion in warm
chloride environments, and to stress corrosion cracking above about
600C. Considered resistant to potable water with up to about
200mg/L chlorides at ambient temperatures, reducing to about
150mg/L at 600C.
