Material introduction:

Inconel 625 is a corrosion and oxidation resistant nickel alloy that is used both for its high strength and outstanding aqueous corrosion resistance. Its outstanding strength and toughness is due to the addition of niobium which acts with the molybdenum to stiffen the alloy's matrix. Alloy 625 has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions. This nickel alloy has excellent weldability and is frequently used to weld AL-6XN. This alloy resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion. Some typical applications Inconel 625 is used in are chemical processing, aerospace and marine engineering, pollution-control equipment, and nuclear reactors

In what applications is Inconel 625 used?

· Aircraft ducting systems

· Aerospace

· Jet engine exhaust systems

· Engine thrust-reverser systems

· Specialized seawater equipment

· Chemical process equipment

Fabrication with Inconel 625

Alloy 625 has excellent forming and welding characteristics. It may be forged or hot worked providing temperature is maintained in the range of about 1800-2150° F. Ideally, to control grain size, finish hot working operations should be performed at the lower end of the temperature range. Because of its good ductility, alloy 625 is also readily formed by cold working. However, the alloy does work-harden rapidly so intermediate annealing treatments may be needed for complex component forming operations. In order to restore the best balance of properties, all hot or cold worked parts should be annealed and rapidly cooled. This nickel alloy can be welded by both manual and automatic welding methods, including gas tungsten arc, gas metal arc, electron beam and resistance welding. It exhibits good restraint welding characteristics.

Characteristic as below:
1. Excellent corrosion resistance of different kinds of media in both oxidation and reduction environments.

2. Excellent resistance of pitting and crevice corrosion, and won't happen stress corrosion cracking because of chloride.

3.Excellent resistance of the inorganic acid corrosion performance, such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid and the mixture of sulfuric acid and hydrochloric acid.

4. Excellent corrosion resistance of different kinds of inorganic acid mixture performance.

5. Good corrosion resistance of a variety of concentrations of hydrochloric acid when the temperature up to 40℃ .

6. Good machining and welding, no weld cracking sensitivity.

7. Have pressure vessel authentication for the wall temperature between -196450℃ .

8. Apply for the highest standard lever VII of acidic environment by the NACE ( MR-01-75)authorized.

Inconel 625 Metallurgical structure
625 is face-centered cubic lattice structure. Dissolve out the carbon granule and instability quaternary phase, then change it to stability Ni3 (Nb,Ti) trimetric lattice around 650℃ after a long time heat preservation. nickel-chromium content will strength the mechanical performance in the state solution while suppress the plasticity.

Inconel 625 Corrosion resistance

625 own a very good corrosion resistance in many media, especially with excellent resistance to pitting, crevice corrosion, intercrystalline corrosion, and erode in oxide, also good resistance to inorganic acid corrosion, such as nitric acid, phosphoric acid, sulfuric acid and hydrochloric acid. 625 can resist the alkali and organic acid corrosion in the oxidation and reduction environment. Effect resists the chloride reduction stress corrosion cracking. Normally no corrosion in the sea-water and industry environments since high corrosion resistance to the sea-water and salting liquid,as well as in high temperature, without sensitivity during welding. 625 have the resistance to oxidation and carbonizing in the static and cycle environments, also hacve the resistance the chlorine corrosion.

Inconel 625 Typical application field as below:

1 .The Organic chemical process parts contains chloride, especially in the use of acid chloride catalyst.

2. The digester and bleacherin the use of paper pulp and paper making industry.

3.Absorption tower, re-heater,gas import board, fan, blender, fair water fin, flue and so on for using in flue gas desulfurization system.

4. The equipment and parts in the use of acidic gas environments.

5. Acetic acid and anhydride reaction generator
6. Sulfur acid cooling
