Product Description

 19309S/0Cr23Ni13/S30908 Stainless Steel Seamless Pipe Type Pipeline
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.

Heat Treatment:

  • They cannot be hardened through heat treatment because they consist solely of austenite at room temperature
  • Higher tensile and yield strengths can be obtained through cold working

Fabrication:

  • Can be roll formed, stamped, and drawn readily
  • In process annealing is often required to reduce hardness and increase ductility

Applications:

309 / 309S stainless steel pipes and tubes are used exclusively for their excellent oxidation resistance, and strength at high temperatures. Additionally, they offer good resistance to creep deformation and extreme environment. Some examples include, but are not limited to:

  • Heating elements
  • Aircraft and jet engine parts
  • Heat exchangers
  • Carburizing annealing products
  • Sulfite liquor handling equipment
  • Kiln liners
  • Boiler baffles
  • Refinery and chemical processing equipment
  • Auto exhaust parts
