inconel 625 is a high-performance nickel alloy that provides excellent corrosion resistance at extremely high temperatures and pressures. It also has an abundance of physical and mechanical properties that make it an ideal material for a number of applications across multiple industries.

Alloy 625 (UNS N06625, 2.4856) is an excellent choice for applications that require a high degree of corrosion and oxidation resistance. It can be used in a variety of applications including marine, chemical processing and nuclear energy equipment.

This super-alloy has a good resistance to pitting, crevice and intercrystalline corrosion as well as chloride-induced stress corrosion cracking. It also has a great deal of ductility and tensile strength at both low and high temperatures and pressures.

Due to its high resistance to a wide range of corrosive environments, this nickel-based alloy is often used in the oil and gas industry for hydraulic systems, turbine blades and compressor casings. It is also a common material for seawater systems on offshore platforms and power and processing plants that use seawater as a coolant.

A number of AM processes are available for producing this alloy. One popular method is the Wire and Arc Additive Manufacturing (WAAM) process. This process uses a wire as a feed material, and an electric arc is used to melt the wire to deposit layers of material on a base plate.

In addition to these conventional methods, a recent study has shown that L-PBF and L-DED processes can be used for fabricating IN625 in a post-built condition. These processes are characterized by rapid melting followed by rapidly cooling during solidification. During L-PBF and L-DED processing, fine dendritic microstructure is deposited on the surface of the powder.
