N08800 is a low-carbon version of Alloy 800 austenitic nickel-iron-chromium alloy. The grade is used for steam generator tubing in nuclear stations (PWR) and other heat exchangers for temperature up to about 550°C (1020°F) where good resistance to stress corrosion cracking (SCC) and intergranular corrosion is required.
