309 seamless stainless steel pipe
309 is an austenitic chromium-nickel stainless steel known for its high corrosion resistance and strength. 309 has the same machining properties as 304, and can be roll formed, stamped, and drawn easily.
Due to its properties, especially its ability to work under high-temperatures, you will find 309 in a wide variety of applications including:
Boiler baffles, furnace components, oven lining, fireboxes, kiln Liners, sulfite liquor handling equipment, carbuizing-annealing boxes, heat exchangers, aircraft engines, automotive exhaust parts
