The Premium 309S Cold Rolled Stainless Steel Sheet/Plate/Coil is a high-alloy austenitic stainless steel specifically engineered for excellent oxidation resistance at elevated temperatures—up to 1000°C (1832°F). Here’s a detailed overview of its key features and applications:


Key Characteristics of 309S Stainless Steel:

  • Grade Type: Austenitic stainless steel
  • UNS Number: S30908
  • Low Carbon Variant: The "S" in 309S denotes lower carbon content (≤0.020%) compared to standard 309, which minimizes carbide precipitation during welding and improves weldability and high-temperature performance.
  • High Chromium & Nickel Content:
    • Cr: ~22–24%
    • Ni: ~12–15%
      → Enhances oxidation and corrosion resistance, especially in high-heat environments.

Advantages:

  • Outstanding Oxidation Resistance: Stable and protective oxide layer forms at temperatures up to 1000°C, making it ideal for continuous high-temp service.
  • Good Sulfidation Resistance: Performs well in sulfur-containing atmospheres.
  • Excellent Creep Strength: Maintains mechanical integrity under prolonged thermal stress.
  • Weldability: Low carbon content reduces risk of intergranular corrosion after welding.
  • Cold Rolled Finish: Offers superior surface finish, dimensional accuracy, and mechanical properties compared to hot-rolled products.

 Common Applications:

  • Furnace components (muffles, retorts, radiant tubes)
  • Heat exchangers and recuperators
  • Exhaust systems and manifolds
  • Thermal processing equipment
  • Petrochemical and power generation industries

Available Forms:

  • Sheet: Thin gauges, typically <6 mm
  • Plate: Thicker sections, >6 mm
  • Coil: Continuous rolled form for fabrication or further processing

 Limitations:

  • Not recommended for use in strongly reducing acids (e.g., sulfuric acid).
  • Lower strength than some heat-resistant alloys (e.g., Inconel) above 1000°C.
  • Susceptible to sigma phase embrittlement if held long-term between 600–900°C.

If you're sourcing or specifying 309S cold-rolled stainless steel, ensure compliance with standards such as ASTM A240/A240M (for plate/sheet/coil) and verify mill test reports for chemistry and mechanical properties.

Let me know if you need technical data sheets, equivalent grades (e.g., EN 1.4833, JIS SUS309S), or supplier recommendations!
