Description

309S Austenitic Stainless Steel Plate for Heat Treatment Furnaces

Our 309S Stainless Steel Plate is a high-chromium, high-nickel austenitic stainless steel engineered for superior oxidation resistance in elevated temperature environments up to 1000°C. The low carbon variant prevents sensitization during welding and high-temperature service. The No.1 hot rolled finish is ideal for furnace components, heat treatment fixtures, and thermal processing equipment. Available from 3mm to 40mm thickness.

Key Features

  • Superior Oxidation Resistance: 23Cr-13Ni composition resists scaling up to 1000°C in continuous service
  • Low Carbon Content: 309S variant (≤0.08% C) minimizes carbide precipitation during welding
  • Good High-Temperature Strength: Maintains structural integrity under thermal cycling conditions
  • Excellent Sulfidation Resistance: Performs well in sulfur-containing atmospheres common in petrochemical processes

Applications

  • Heat treatment furnace linings and components
  • Annealing boxes and baskets
  • Burner components and flame tubes
  • Cement kiln and lime kiln internals
  • Petrochemical heater tubes and supports
  • Waste incineration plant components
