Introduction to Inconel625 Alloy

Inconel 625

It is a high-performance product

nickel-chromium-molybdenum alloy

This alloy is known for its high strength and resistance to corrosion. Superalloys are mainly made of nickel (min. 58%, followed closely by chromium (min.

Inconel 625 Alloy Properties

Special material strength

Inconel 625 has a strength that is due not only to its Ni-Cr matrix, however it also depends on the hardening mechanism of molybdenum and niobium. The interaction between niobium, molybdenum makes the alloy matrix stronger and offers high strength without precipitation. The alloy has a yield strength of 690 MPa and a tensile resistance of 275 MPa.

High resistance to heat

The Inconel 625 has an approximate melting point of 1300 degC and a thermal extension coefficient of 1.28×10-5/K (at 20degC), making it resistant to extreme temperatures.

Inconel 625 is formed naturally by a protective layer when there is an oxidizer at high temperatures. The titanium and the niobium elements of the oxide film on Inconel 625 are dramatically increased.

The corrosion resistance

Inconel 625 is extremely resistant to corrosive substances due to the unique combination it contains. This is why the superalloy performs well in salty seawater, even in milder conditions such as fresh water or standard atmospheric conditions.

Nickel-chromium’s nickel-chromium substrate protects Inconel 625 from oxidants. The material is also protected from pitting by molybdenum. 15% sulfuric acid has a min. Material corrosion occurs at 0.188mm per annum in 15% sulfuric acid.

High production capability

Inconel 625 was developed to be more weldable than other alloys. There are no signs of cracking after welding, and it is resistant to heat and strain. This superalloy is excellent for welding pipe, piping, and other factory equipment.

Inconel 625 Alloy Application

Inconel 625, a material that can be used in steam pipes, was developed in the 1960s. To make it more resistant to creep and easier to weld, some modifications were made to the original composition. Inconel 625 has been used in many industries including the chemical processing industry as well as Marine and Nuclear applications for manufacturing pumps and valves as well as other high-pressure equipment.

Inconel alloy 625 has remarkable resistance to corrosion and oxidation. It is strong enough to withstand high stresses in water, at all temperatures, and it resists corrosion in acidic environments. This makes Inconel alloy 625 a good choice for Marine and Nuclear applications.

Alloy 625 has many applications in various industries such as automotive, aerospace, marine, aviation, oil and gaz, chemical processing, and nuclear. Heat exchangers, bellows and expansion joints are some of the most common applications.
