Stainless Steel 309 Flanges are flanges made from stainless steel grades 309 and 310. These grades are austenitic stainless steels that offer excellent high-temperature strength and resistance to oxidation and corrosion, making them suitable for use in elevated-temperature applications.

The chemical composition of Stainless Steel 309 typically includes around 22-24% chromium and 12-15% nickel, along with small amounts of manganese, silicon, and carbon. Stainless Steel 310 has a similar composition but with a higher chromium content (24-26%) and added silicon (1.5-2.5%). The elevated chromium and nickel content in both grades contributes to their exceptional resistance to oxidation and carburization at high temperatures.

One of the key features of Stainless Steel 309/310 Flanges is their high-temperature strength and thermal stability. They can withstand temperatures up to 1100°C (2012°F) in continuous service and up to 1150°C (2102°F) in intermittent service, making them ideal for use in heat treatment, furnace components, and other high-temperature applications.

Stainless Steel 310 Flanges also exhibit good resistance to corrosion in various environments, particularly in moderately oxidizing and reducing conditions. However, they may experience reduced performance in chloride-rich or highly acidic environments, and as such, they are not recommended for applications where exposure to these conditions is prevalent.

 Stainless Steel 310 Flanges

Regarding heat treatment, Stainless Steel 309/310 Flanges are generally not heat treatable as they are primarily used in the annealed condition. However, they can be subjected to solution annealing treatment to relieve stresses after fabrication.

These flanges find applications in various high-temperature industries such as heat treatment, petrochemical, and chemical processing. They are commonly used in combustion chambers, kilns, and other furnace components. Stainless Steel 309/310 Flanges are also employed in exhaust systems, radiant tubes, and fluidized bed combustors.
