Inconel 600

Inconel 600 is a nickel-chromium alloy with good oxidation resistance at higher temperatures, with good resistance in carburizing and chloride containing environments. Inconel 600 is a nickel-chromium alloy designed for use from cryogenic to elevated temperatures in the range of 2000 deg F(1093 deg C).

Inconel 600 Characteristic as below:

  • Good corrosion resistance property for the reduction, oxidation, Nitric and other media.
  • Good stress corrosion cracking resistance property in both room temperature and high temperature.
  • Good corrosion resistance of the dry chlorine and chlorine hydride.
  • Good mechanical property when below zero, room temperature and high temperature.
  • Good anti-creep rupture strength, with the recommendation of 700℃ or above working environment.

Inconel 600 Metallurgical structure

600 is face-centered cubic lattice structure.


Inconel 600 Corrosion resistance

600 have corrosion resistance to many kinds of corrosive media. Chromium content made it with better corrosion resistance than Nickel 99.2 (alloy200) and Nickel 99.2 ( alloy201,low carbon) in the oxidize environment. Meantime, high Nickel content make this alloy with good corrosion resistance in the reduction condition and alkaline solution, and also effective avoid chlorine-iron stress corrosion cracking. 600 have good corrosion resistance in the acid, acetic acid, formic acid, stearic acid and other organic acid, with medium corrosion resistance in the inorganic acid. The alloy with excellent corrosion resistance in the first and the second recycling use of the high purity water in the nuclear reactor. Especially excellent corrosion resistance to dry chlorine and chlorine hydride applied up to 650 . When nder the high temperature, annealing and state solution alloy have good antioxidant off and high-intensity in the air, 600 can resist the ammonia, nitriding and carburizing atmosphere, but at the turn of the changes in redox conditions, it will be corrosion by parts of oxidation media.( such as green death liquid)

Inconel 600 Application field:
  • Erosion thermocouple sheath of the atmosphere
  • Vinyl chloride monomer production: corrosion resistance to chlorine, hydrogen chloride, oxidation and carbonation.
  • Oxide shaft chloride converted to six fluoride: hydrogen fluoride anti-corrosion.
  • Corrosive alkali metal produce and usage filed, especially the sulfide use environment.
  • Use Chlorine produce titanium dioxide
  • Organic or inorganic chlorine produce: corrosion resistance to chlorine and fluoride.
  • Nuclear reactor
  • Heat treatment furnace flask and components, especially in the carbonization and nitride atmosphere.
  • Petrochemical works production of catalytic regeneration in the application of more than 700℃ recommended the use of 600, in order to obtain a longer service life.
