Are used for their high resistance to corrosion in offshore platforms, desalination plants and equipment, as well as in power and process plants that use seawater as coolant,
INCONEL® alloy 625 is an excellent choice for sea-water applications, as it is resistant to pitting and crevice corrosion and has high corrosion-fatigue strength, high tensile strength, and is resistant to chloride-ion stress-corrosion cracking. Used in wire rope, propeller blades, propulsion motors and sheathing for undersea communication cables, this versatile alloy has earned its place in the marine industry.
Down-hole equipment, like hangers, uses another super alloy, INCOLOY® alloy 718 for its high strength and corrosion resistance.
MONEL alloy 400® is a nickel-copper alloy that is stronger than pure nickel and can be fabricated readily by hot- and cold-working, machining, and welding. MONEL alloys are resistant to corrosion by many agents, including rapidly flowing seawater. This feature, coupled with its resistance to bio-fouling and microbially induced corrosion (MIC), makes MONEL a cost-effective and robust alloy for the manufacture of wave protection sheathing for platform risers and steel pylon legs on offshore rigs.
Alloys in the INCONEL series are often encountered in extreme environments. These super alloys are oxidation and corrosion resistant and well-suited for service in extreme environments.
A newer alloy, INCONEL® alloy 725, offers even more corrosion resistance. A nickel-chromium-molybdenum-niobium alloy, it is highly resistant to corrosion and hardens with age, which increases its strength. INCONEL® alloy 725 is resistant to hydrogen embrittlement and stress-corrosion cracking, making it ideal for the manufacture of hangers, and high-strength fasteners in marine applications
