Product Details
Stainless steel 309 and 309S are austenitic chromium-nickel stainless steels that are often used for higher temperature applications. Due to their high chromium and nickel content, Alloys 309 and 309S are highly corrosion resistant, have outstanding resistance to oxidation, and excellent heat resistance while providing good strength at room and elevated temperatures. The only significant difference between 309 and 309S is the carbon content. Alloy 309S has a much less carbon composition which minimizes carbide precipitation and improves weldability.
Shape: Round, Square, Rectangular, Hexagonal, Slot, Oval, etc
Outer Diameter:
1) Round pipe: 8mm to 680mm
2) Square pipe: 10x10mm to 300x300mm
3) Rectangular pipe: 10x20mm to 120x180mm
1) Seamless pipe: 0.6mm – 30mm
2) Welded pipe: 0.5mm – 25mm
Application: Decoration, construction, upholstery, industry instrument, medical equipment, seawater environment, petrochemical, fertilizer, oil refining, oil and natural gas, light/food, paper pulp and making paper, energy and environmental protection industry, ect
