Product Application Areas :
Heat Exchanger, Refineries, Power Plants, Condensors, Ship Building & ship Repairs, Offshore Oil rigs, Car Braking Systems, Desalination Plants etc.

Characteristics :
This alloy has very high erosion and corrosion resistance. It has very high weldability, easy for installation and high antifouling properities against sea microorganisms. Relatively high iron content provides better impingement attack resistance. The alloy is unique to stress corrosion cracking.

Guide to the selection of tube material :

Sea Water-

  • Dissolved salts from 1500 to 3000 ppm.

  • Suspended solids more than 25 ppm.

  • H2S or Ammonia less than 1 ppm.

Permissible average velocity of water 2.5- 2.7 metres/sec.
