Introduction
N08811, also known as Incoloy 800HT, is an improved high-temperature nickel-chromium-iron alloy with appropriate amounts of molybdenum, copper and aluminum. This chemical combination provides good corrosion resistance and high-temperature stability. The structural stability of the alloy enables it to exhibit better performance at high temperatures. Compared with Incoloy 800 and 800H, N08811 has better structural stability and creep resistance at high temperatures. It is particularly suitable for high temperature and corrosive environments.
