309S seamless stainless steel pipe
309S stainless steel is a low carbon version of 309. Because of its lower carbon-content, 309S minimizes carbide precipitation, and improves weldability. It can be easily roll formed, stamped and drawn. Other key properties of 309S include good weldability and machinability, outstanding resistance to oxidation. 309S is utilized by many different industries for a number of critical applications including:oven Linings, boiler baffles, firebox sheets, furnace components, most high temperature containers, aircraft and jet engine parts and so on.
