Marine Engineering

The Standard Since 1906

With its resistance to corrosion by rapidly flowing seawater, marine engineering is one of the longest established applications for our MONEL® nickel alloys.


Saltwater Resistance You Can Count On

For a range of engineering projects that span power generation, oil and gas and other industries, our marine engineering alloys set the standard for proven performance.


Primary Uses

Our products are used for their resistance to seawater corrosion in marine and submarine applications.

Multiple Applications

Other applications include offshore platforms and in power and process plants using seawater as a coolant.

Advanced Alloys

INCONEL® alloy 625 is a nickel-chromium-molybdenum alloy that resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion.
