Stainless Steel 309 is an austenitic stainless steel containing around 24–26% chromium and 13–15% nickel that offers excellent oxidation and corrosion resistance at high temperatures. It ensures consistent performance in conditions up to 2010°F (1100°C), which makes it suitable for high heat applications. The tubing has superb weldability, formability, and strength, as well as resistance against carburization and scaling. Its stress stability and thermal conductivity enable it to have long-term efficiency in extreme operating conditions. These properties guarantee long term performance, especially in those industries calling for toughness and durability in extreme temperatures.
