Typical Application
Components with high resistance to corrosion, erosion and cavitation particularly in marine and offshore environments
Drinking water treatment systems
Typical Components
Components for piping systems and plant engineering, particularly in seawater-carrying installations, such as fittings including flanges, valves, connectors and joint elements
Plates and tube sheets for heat exchangers and condensers, as well as feedwater preheaters (low pressure), freshwater generators, air conditioning systems, process equipment, finned tubes and brake lines
High-quality alternatives for bolts and nuts, particularly as an upgrade where corrosion-related loads exceed the performance limits of nickel aluminium bronzes
