Metallographic structure of Inconel 600.

Inconel 600 is a face-centered cubic lattice structure.

Corrosion resistance of Inconel 600.

Inconel 600 is corrosion resistant to a wide range of corrosive media. The chromium composition gives the alloy better corrosion resistance under oxidizing conditions than nickel 99.2 (alloy 200) and nickel 99.2 (alloy 201, low carbon). Also, the higher nickel content gives the alloy good corrosion resistance under reducing conditions and in alkaline solutions, and provides effective protection against chlorine-iron stress corrosion cracking. Alloy 600 has good corrosion resistance in organic acids such as acetic acid, acetic acid, anthranilic 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 loops in nuclear reactors. 600 is particularly outstanding in its ability to resist corrosion by dry chlorine gas and hydrogen chloride at application temperatures up to 650°C. At high temperatures, the alloy in the annealed and solution-treated states has excellent resistance to oxidation spalling and high strength in air. The alloy is also resistant to ammonia and nitriding and carburizing atmospheres, but is subject to corrosion by partially oxidizing media when redox conditions alternate (e.g., green death fluids)

Application of Inconel 600

1.Thermocouple sleeves in erosive atmospheres.

2.Vinyl chloride monomer production: resistance to chlorine, hydrogen chloride, oxidation and carbonation corrosion.

3.Uranium oxidation conversion to hexafluoride: resistance to hydrogen fluoride corrosion.

4.Corrosive alkali metal production and use areas, especially the use of sulfide environment.

5.Titanium dioxide production by chlorine gas method.

6. Production of organic or inorganic chlorides and fluorides: resistance to chlorine and fluorine corrosion.

7.Nuclear reactors.

8.Heat treatment furnace bent neck bottle and parts, especially in the carbonization and nitriding atmosphere.

9.Catalytic regenerators in petrochemical production in applications above 700°C. Inconel 600 is recommended to obtain a long service life.
