Grade 309 are austenitic chromium-nickel stainless steels, which are often used for high temperature applications. Due to their high chromium and nickel content, Grade 309 pipes are highly corrosion resistant, and have outstanding resistance to oxidation. In addition, they exhibit excellent heat resistance while providing good strength at ambient or elevated temperatures.
