Extruded finned tubes manufactured with ASTM B163 / ASME SB163 UNS N08825 (Incoloy 825) base material are engineered for highly corrosive seawater and marine cooling environments. The metallurgical bonding between the aluminum fin and the nickel-iron-chromium alloy tube ensures excellent heat transfer efficiency while maintaining long-term resistance to chloride-induced corrosion, pitting, and stress corrosion cracking.
This product is widely used in seawater-based cooling systems where conventional stainless steels are insufficient due to aggressive chloride exposure and fluctuating salinity conditions.
ASTM B163 N08825 extruded finned tubes are widely used in:
