UNS S30909 Pipe & AISI 309H Seamless Tubing manufacturer

UNS S30909 Tubing is a high carbon development of the 309 material. The 309 is an austenitic stainless steel grade that has high temperature resistance. It has carbon, manganese, silicon, 22% chromium, 12% nickel, molybdenum, phosphorus, sulfur, copper and iron for the balance of the composition. the AISI 309H Welded Tube and seamless piping have very high corrosion resistance compared to the 304 and 316 austenitic stainless steel grades. It is also denser than the lower grades of austenitic stainless steels. The melting range of the pipes is between 1399 to 1454 degrees Celsius. There are round, square, rectangular and hydraulic pipe types among which the 309S Stainless Steel Pipe is the most used. The other shapes are used in specific situations.

The square pipe is used when high strength and lightweight are required by the application. The pipe has 620 MPa minimum tensile strength and 205 MPa minimum yield strength. These high strength values allow the pipes to be used in high strength applications. The pipes range from ¼ inches to 48 inches inn outer diameters. There are different pipes such as the Stainless Steel 309H lined pipe which is a high carbon version to improve the toughness of the pipes. The applications include oil and gas, petroleum, food processing, pharmaceutical and ship building. Since the pipes have high temperature resistance, the 309H SS Heat Exchangers Tubes are used with heat exchanger, boiler and condenser applications to withstand high temperatures. Compared to high metal alloys, these pipes are very much cost efficient.
