Alloy 600, also known as Inconel 600, is a nickel-chromium alloy known for its excellent resistance to high-temperature corrosion and oxidation.
It belongs to the Inconel family of alloys, which are renowned for their exceptional performance in challenging environments. Alloy 600 is composed primarily of nickel (around 72%) and chromium (about 15%), with smaller amounts of iron, as well as additional elements such as manganese and copper.
Alloy 600 is specifically designed to maintain its mechanical integrity and resist corrosion at elevated temperatures. It can withstand temperatures ranging from cryogenic levels to around 1093°C (2000°F).
Alloy 600 exhibits good resistance to a wide range of corrosive environments, including nitric and sulfuric acids, alkaline solutions, and various gases.
