Inconel 600

Inconel600(UNS 6600)
he alloy is a nickel-chromium-iron-based solid solution strengthening alloy with excellent high temperature corrosion resistance and oxidation resistance, excellent cold and hot processing and welding properties, and satisfactory thermal strength and high plasticity below 700℃. Alloys can be strengthened by cold processing, or can be connected by resistance welding, dissolving welding or brazing, suitable for making antioxidant parts under 1100℃ under low load.

Inconel600 corrosion properties

Medium

For normal temperature sulfuric acid, the respective concentrations of normal temperature phosphoric acid, acetic acid, fatty acids and other organic acids have good corrosion resistance, can withstand the corrosion of dry chlorine gas and hydrogen chloride, in the alkali has a corrosion resistance. Can also be used in high temperature, oxidation, hot alkali, alkali sulfides, hydrogen fluoride, reducing environment and other media

can not be used for high temperature hydrofluoric acid and high concentration hydrochloric acid, which can produce stress corrosion in high temperature strong alkali solution. Therefore, the workpiece should eliminate the stress as far as possible.
