309S Stainless Steel Pipe
309S Stainless Steel Pipe is the low-carbon version of Grade 309, offering excellent weldability and superior resistance to oxidation at high temperatures (up to 1830℉ or 980℃). Its high chromium/nickel content provides better heat resistance than 304. This pipe is essential for high-temperature service in furnace parts, boiler components, and heat exchangers where reliable welding and heat stability are critical.
