Alloy 600 • UNS N06600 • WNR 2.4816 Material
Nickel alloy 600 consists mainly of nickel (about 72%) and chromium (about 15%), with a small amount of iron, and additional elements such as manganese and copper. UNS N06600 is a nickel-chromium alloy known for its excellent high temperature corrosion and oxidation resistance. W. Nr 2.4816 can work for a long time below 1093°C (2000°F).
