However, slight variations in nickel content can affect the strength of the final product. The alloy can also be hot forged. The furnace temperature for hot forming should be between 1700 deg and 2150 degC.

Non-magnetic

Typical applications of Inconel 625 alloy include marine engineering, chemical processing, gas turbines, and down-hole equipment. The alloy has a high level of oxidation resistance and corrosion resistance. In addition to these, Inconel 625 also has high strength and fatigue resistance.

The alloy's strength is derived from the fact that it has a solid solution strengthened matrix of nickel and chromium. This matrix gives the alloy good toughness and stress-corrosion cracking resistance to chloride ions. The high amount of molybdenum in the alloy ensures that it is highly resistant to crevice corrosion.

It is used in the aerospace industry, as well as in gas turbines and high-performance sports cars. It is also used in the nuclear energy field. In addition to its corrosion resistance, Inconel 625 has outstanding tensile strength, high fatigue strength, and good weldability. It is also resistant to corrosion, oxidation, and carburization.

This alloy has a low carbon content, which prevents carbide precipitation during welding. Its resistance to oxidation and carburization at high temperatures also makes it useful for high-strength fasteners. It is also a good choice for high-wear applications.

Alloy 625 is highly resistant to oxidation, crevice corrosion, and stress corrosion cracking. It also has excellent thermal fatigue strength. It is also used in gas turbines, chemical processing equipment, and waste handling facilities.

Inconel 625 alloy is a nickel-chromium-molybdenum superalloy. It is used in a variety of applications, including marine engineering, chemical processing, gas turbines, down-hole equipment, and high-performance sports cars.

Corrosion resistance

Various aspects related to the corrosion resistance of Inconel 625 are studied. These include its oxidation resistance, crevice corrosion, pitting corrosion, and stress corrosion cracking. Compared to Inconel 600, the corrosion resistance of Inconel 625 is higher. It can be used in marine and aerospace industries.

In order to improve the corrosion resistance of Inconel 625 coating, high speed laser cladding technique was used. This technique significantly improves the corrosion resistance. The process was optimized to achieve maximum corrosion resistance. The coatings were processed at ultra-low dilution rate. The dilution ratio was 12%. The coatings had a thickness of 534.4 mm.

The cladding was tested in de-aerated 3.5 wt% NaCl solution. The corrosion performance of the wire laser clad Inconel 625 coating was compared to the wrought Inconel 625 alloy. The results showed that the wire laser clad Inconel-625 coatings had higher corrosion resistance than the wrought Inconel-625 alloy. It is possible that the cladding process may have altered the chemical composition. The clad layer may be formed with a hexagonal close-packed structure. The resulting surface finish is also good.

Microstructure of the clad beads was investigated by optical and scanning electron microscopy. These results showed that the clad beads had crack-free microstructure. It was also observed that the clad beads had a flat top surface. The top surface of the clad beads had a corrosion product thickness of 0.1 mm. The corrosion product may be due to the formation of a dense silicon oxide protective film. The results were verified by chemical analysis.

The cladding process was optimised to achieve maximum corrosion resistance. The dilution ratio of Fe was determined to be 12%. The corrosion performance of the wire laser nitinol Inconel-625 coating was lower at 12% dilution.
