Introduction to Inconel625 Alloy

Inconel 625

It is a high-performance product

nickel-chromium-molybdenum alloy

This alloy is known for its strength, resistance to temperature and resistance to corrosion. Superalloys are mainly composed 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 the NiCr matrix but also to the hardening mechanism between niobium, molybdenum. 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 temperature resistance

The Inconel 625 is extremely resistant to extreme temperatures. It has a melting temperature of about 1300°C and a thermal extension coefficient of 1.28×10-5/K (at 20degC).

Inconel 625 is formed naturally by a protective layer when it is treated with an oxidizer at high temperatures. The titanium and the niobium elements of the oxide film on Inconel 625 are dramatically increased in presence of an oxidizer at very high temperature.

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 water, particularly in milder environments like fresh water or normal atmospheric conditions.

Nickel-chromium’s nickel-chromium substrate protects Inconel 625 from oxidants. The material is also protected from pitting by molybdenum. The minimum. Material corrosion occurs at 0.188 mm 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 factory equipment.

Inconel 625 Alloy Application

Inconel 625, a material that can be used in steam pipes, was developed in 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 a variety of industries including the chemical processing industry as well as in marine and nuclear applications to produce pumps and valves as well as other high-pressure equipment.

Inconel alloy 625 has remarkable resistance to corrosion and oxidation. It is capable to withstand high stresses in water and at a wide temperature range. It also resists corrosion when exposed to acidic environments.

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.
