Key Advantages


Superior Seawater Corrosion Resistance


  • Low corrosion rate (<0.025 mm/year) in flowing seawater.
  • Resists pitting and stress corrosion cracking in chloride environments.


Biofouling Resistance


  • Inhibits marine organism attachment – reduces maintenance costs.


High Thermal Conductivity

  • 29 W/m·K (vs. 16 W/m·K for 316 stainless steel) – ideal for heat exchangers.


Erosion Resistance

  • Withstands high-velocity seawater (up to 3.5 m/s).



Application Fields

Critical Applications


Marine Engineering


Shipboard condensers, seawater piping, desalination plants


Power Generation


Steam condenser tubes, heat exchanger tubing


Oil & Gas


Offshore platform cooling systems, brine heat exchangers
