The chemical composition of C625, also known as Inconel 625, is as follows:
– Nickel (Ni): 58.0% min
– Chromium (Cr): 20.0-23.0%
– Molybdenum (Mo): 8.0-10.0%
– Iron (Fe): 5.0% max
– Niobium (Nb) + Tantalum (Ta): 3.15-4.15%
– Carbon (C): 0.10% max
– Manganese (Mn): 0.50% max
– Silicon (Si): 0.50% max
– Phosphorus (P): 0.015% max
– Sulfur (S): 0.015% max
C625 also contains small amounts of other elements such as aluminum, titanium, and cobalt.
The unique combination of elements in C625 provides it with excellent resistance to corrosion and high-temperature stability, making it a popular choice for various applications in the chemical processing, oil and gas, and aerospace industries.
