The Application of Nickel Alloy in Marine Vessels

Nickel alloy has become a preferable material used in marine vessels due to its outstanding properties. It is corrosion-resistant, able to withstand high temperatures and pressure, and has excellent mechanical strength. The application of nickel alloy in marine vessels contributes substantially to the safety, durability, and longevity of vessels.

Many critical parts of marine vessels use nickel alloy, such as engine exhaust systems, seawater cooling systems, and piping systems. The significant advantage of nickel alloy lies in its excellent anti-corrosion ability against seawater and marine organisms such as barnacles and mussels. Furthermore, the material's high temperature and pressure resistance make it ideal for high-temperature steam pipes, boilers, and turbines, which are necessary for the vessel's efficient operation.
