Inconel Alloy 625 (UNS designation N06625) is a Ni-Cr based superalloy that possesses
high strength properties and resistance to elevated temperatures. It also demonstrates
remarkable protection against corrosion and oxidation. Its ability to withstand high stress
and a wide range of temperatures, both in and out of water, as well as being able to
resist corrosion while being exposed to highly acidic environments makes it a fitting
choice for nuclear and marine applications.
Inconel 625 was developed in the 1960s with the purpose of creating a material that
could be used for steam-line piping. Some modifications were made to its original
composition that have enabled it to be even more creep-resistant and weldable.
Some chemical properties of Inconel 625 include:
Inconel 625 was designed as a solid solution strengthened material with no significant
microstructure. This holds true at low and high temperatures, but there is a region
(923 to 1148 K) where precipitates form that are detrimental to the creep properties,
and thus the strength, of the alloy. Under any creep conditions (high temperature
with an applied stress), M23C6-type carbides form at the grain boundaries. When
tested at 973 K, γ” precipitates begin forming. These γ” phase precipitates are
ordered A3 B type with a composition of Ni3(Nb, Al, Ti) and a tetragonal crystal structure.
They form a disk-shaped morphology and are coherent with respect to the matrix.
When tested at 998 K, a δ-phase precipitate begins forming which consist of Ni3(Nb, Mo)
in an orthorhombic crystal structure. They form in a needle-like morphology and are
incoherent with the matrix. Both of these precipitates can be completely dissolved back
into the matrix when the sample is heated 1148 K. This leads to the ability to recover creep
properties of the alloy to prolong the materials lifetime.

Specifications and certifications include:
Heat Treatment Inconel 625 is usually strengthened by cold work, with annealing at
temperatures between 1,700 and 1,900F as required to remove the effects of cold work.
Although nominally a solid-solution alloy containing intergranular and intragranular
carbide precipitates, Inconel 625 is not responsive to strengthening heat treatments.
Solution heat treating at 2000 to 2200F dissolves almost all of the secondary carbides.
The major effects of short-time annealing of hot-rolled bar of standard composition are
to affect reductions in tensile strength and hardness.Typically, the annealing heat
treatment most utilized for Inconel 625 is at 1800F.
