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).
