A pipe without a seam or weld is known as Seamless Pipe. 309 Seamless Pipes can withstand high mechanical stress and high pressure can work in high temperatures and corrosive environments. Stainlesss Steel Seamless Pipe is formed by drawing a solid metal billet over a piercing rod to create a hollow tube. Seamless Pipe is then processed and finished as per dimension standard ANSI B36.10 and ANSI B36.19 and B36.19M in different wall thickness and sizes ranging from SCH 5S to SCH XXS. Seamless Pipes have varied applications in the Oil and gas, Chemical, Pharmaceutical, Fertilizer, Agro-Chemical, Aerospace, Desalination, Food and Beverage, Sugar, Distillery, Power Generation, Cement, Petroleum Refinery, mechanical and structural, food processing, etc.

Properties of AISI 309 Stainlesss Steel
309 SS Cold Forming
The alloy is quite ductile and forms in a manner very similar to 316. Cold forming of pieces with long-term exposure to high temperatures is not recommended since the alloy is subject to carbide precipitation and sigma phase precipitants.
309 SS Hot Forming
Heat uniformly at 1742 – 2192°F (950 – 1200°C). After hot forming a final anneal at 1832 – 2101°F (1000 – 1150°C) followed by rapid quenching is recommended.
309 SS Welding
Alloy 309 can be readily welded by most standard processes including TIG, PLASMA, MIG, SMAW, SAW and FCAW.
