What is Inconel 600?
INCONEL 600/UNS N06600/DIN 2.4816
What is Inconel 600?
Inconel 600 A nickel-chromium alloy with stable high temperature oxidation resistance. It is also resistant to chloride ion stress corrosion cracking, high purity corrosion, water corrosion and alkali corrosion. This alloy is therefore ideally suited for use in furnace components, chemical and food processing, nuclear engineering and spark electrodes.
What makes it so special?
The chromium content makes the alloy resistant to sulfur compounds and other oxidizing conditions. The chromium content in Inconel 600 makes it ideal for commercially pure nickel in oxidizing environments. It is relatively unhindered by most alkaline and neutral salt solutions.
Where is Inconel 600 used?
Inconel 600 is used and applied by multiple industries. It involves process equipment such as fluorination and chlorinated hydrocarbon production. Manufacturers of heat exchangers and reaction vessels like to use this alloy, especially in the construction of vinyl chloride and other substances.

●Inconel 600 alloy has the following properties:
1. It has good resistance to corrosion by reducing, oxidizing and nitriding media.
2. It has good resistance to stress corrosion cracking at room temperature and high temperature.
3. It has good resistance to corrosion by dry chlorine gas and hydrogen chloride gas.
4. It has good mechanical properties at zero, room temperature and high temperature.
5. It has good creep rupture resistance and is recommended for use in working environments above 700°C.
●Metalographic structure of Inconel 600:
600 is a face-centered cubic lattice structure.
●Corrosion resistance of Inconel 600:
Alloy 600 is corrosion resistant to various corrosive media. The composition of chromium gives this alloy better corrosion resistance under oxidizing conditions than Nickel 99.2 (Alloy 200) and Nickel 99.2 (Alloy 201, low carbon). At the same time, the higher nickel content gives the alloy good corrosion resistance in reducing conditions and alkaline solutions, and can effectively prevent chlorine-iron stress corrosion cracking. Alloy 600 has good corrosion resistance in organic acids such as acetic acid, acetic acid, formic acid, and stearic acid, and moderate corrosion resistance in inorganic acids. It has excellent corrosion resistance in high-purity water used in primary and secondary circulation in nuclear reactors. The particularly outstanding performance of 600 is its resistance to corrosion by dry chlorine and hydrogen chloride, and the application temperature can reach 650°C. At high temperatures, annealed and solution-treated alloys have good resistance to oxidation spalling and high strength in the air. The alloy is also resistant to ammonia gas and nitriding and carburizing atmospheres, but when the redox conditions alternate, the alloy will be corroded by partially oxidizing media (such as green death liquid)
●Inconel 600 Application Scope Application fields include:
1. Thermowells in corrosive atmosphere
2. Vinyl chloride monomer production: resistant to chlorine gas, hydrogen chloride, oxidation and carbonization corrosion
3. Oxidation of uranium into hexafluoride: resistant to hydrogen fluoride corrosion
4. Fields of production and use of corrosive alkali metals, especially environments where sulfides are used
5. Preparation of titanium dioxide using chlorine gas method
6. Production of organic or inorganic chlorides and fluorides: resistance to chlorine and fluorine corrosion
7. Nuclear Reactor
8. Retorts and components in heat treatment furnaces, especially in carbonizing and nitriding atmospheres
9. For catalytic regenerators in petrochemical production, alloy 600 is recommended for applications above 700°C to obtain a longer service life.
