309 Stainless Steel Pipe

309 Stainless Steel Pipe

SS309 pipe is a high temperature resistant stainless steel pipe, composed of about 22% chromium and 12% nickel, suitable for high temperature environments up to 1000°C (1832°F). 309 stainless steel has corrosion resistance comparable to 304, excellent oxidation resistance, and is commonly used in industries such as heating elements, heat exchangers, and refinery building pipelines.

Heat Treatment

Heat Treatment

Stainless steel tubing pipe heat treatment
  1. Solution Annealing
    • Heat the pipe to a temperature of approximately 1040-1150°C (1900-2100°F) and then cool rapidly in water or air.
    • Dissolves any precipitates and relieves internal stresses, improving overall ductility and corrosion resistance.
  2. Stress Relief
    • Heat the pipe to a lower temperature, typically around 675-750°C (1250-1380°F), and then cool slowly.
    • Reduces residual stresses introduced during welding or machining, thereby preventing distortion and improving dimensional stability.
  3. Normalizing
    • Heat the pipe to a temperature above its critical range (approximately 950-1050°C or 1740-1920°F), and then air cool.
    • Refines the grain structure and improves mechanical properties such as toughness and strength.
  4. Quench and Temper
    • Heat to a high temperature, then cool rapidly (quench), then heat again to a lower temperature (temper).
    • This method is not typically used for SS309.

Characteristic

Characteristic

High temperature resistance: SS309 has excellent high temperature resistance and can work stably in environments up to 1000°C (1832°F).
Corrosion resistance: Although the corrosion resistance is better than ordinary carbon steel, it is slightly lower than other stainless steels (such as SS316).
Strength: It has high strength and toughness and can maintain structural stability under high temperature conditions.

Packing

Packing

Our commitment to quality extends to our packaging practices, ensuring your steel pipes arrive in top condition, ready for immediate use. If you have any specific packaging requirements or questions, please let us know and we will be happy to accommodate your needs.

  • Palletized Packaging: Each bundle of our pipes is tightly strapped with durable steel straps to prevent movement and prevent damage during transportation. The bundled steel pipes are securely arranged on sturdy wooden pallets, ensuring easy handling and efficient storage.
  • Steel Pipe Protection: We use high-quality plastic film to wrap the pipes, and protective pads or foam materials at both ends and outside of the pipes to minimize the risk of impact damage and protect against environmental factors such as moisture and dust.
  • Containerized Shipping: For bulk orders or international shipments, we use sturdy containers to provide full protection during long-distance transportation.
  • Labeling and Marking: Each package is clearly marked with basic information such as pipe specifications, quantity and handling instructions to ensure accurate and efficient handling.
  • Anti-corrosion treatment: We use anti-corrosion coatings or protective oils to prevent rust and maintain the integrity of the pipeline, especially for those pipelines transported to wet or corrosive environments.
