AISI ASTM TP 304 304L 309S 310S 316L 316ti 321 stainless steel pipe/stainless steel tube
Grade 309 / 309S are austenitic chromium-nickel stainless steels, which are often used for high temperature applications. Due to their high chromium and nickel content, Grade 309 / 309S pipes are highly corrosion resistant, and have outstanding resistance to oxidation. Also, they exhibit excellent heat resistance while providing good strength at ambient or elevated temperatures. However, the only significant difference between 309 and 309S is the carbon content. Grade 309S stainless steel pipes have a much less carbon composition, which minimizes carbide precipitation, and improves weldability.
