Is Inconel rust proof?
INCONEL and MONEL alloy products are used on offshore platforms and in power plants and process plants that use seawater as coolant due to their high corrosion resistance.
INCONEL series alloys are often encountered in extreme environments. These superalloys are resistant to oxidation and corrosion, making them ideal for use in extreme environments.
A new alloy, INCONEL Alloy 725, offers greater corrosion resistance. It is a nickel-chromium-molybdenum-niobium alloy that is highly resistant to corrosion and hardens over time, increasing its strength. INCONEL Alloy 725 is resistant to hydrogen embrittlement and stress corrosion cracking, making it ideal for manufacturing high-strength fasteners in hangers and marine applications
INCONEL 625 alloy is an excellent choice for seawater applications because of its resistance to pitting and crevice corrosion, high corrosion fatigue strength, high tensile strength, and resistance to chloride ion stress corrosion cracking. Used in steel wire ropes, propeller blades, propulsion motors and undersea communications cable sheathing, this versatile alloy has earned a niche in the marine industry.
Downhole equipment, such as hangers, uses another superalloy, 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 easily manufactured through hot and cold working, machining and welding. Monel alloy can resist corrosion in a variety of media, including fast-flowing seawater. This property, coupled with its ability to resist biofouling and microbially induced corrosion (MIC), makes MONEL a cost-effective and strong alloy for use in the manufacture of wave protection sheathing for offshore drilling platform risers and steel tower legs.
