Alloy 600 is a stable austenitic solid solution material. The high nickel content makes the alloy essentially immune to chloride-ion stress corrosion cracking. The high nickel and chromium contents result in good corrosion resistance to organic and inorganic compounds, and oxidation resistance. The alloy exhibits good high temperature mechanical properties and is used in heat treating applications. The alloy is not precipitation hardenable and can only be strengthened by cold work.
