Heat Treatment
Heat Treatment
- Annealing: Annealing at 1010°C to 1120°C (1850°F to 2050°F) followed by rapid cooling to restore its best mechanical properties and corrosion resistance.
- Solution Annealing: Performed at 1050°C to 1150°C (1920°F to 2100°F) to enhance its corrosion resistance and strength.
- Stress Relief: Performed at 675°C to 760°C (1250°F to 1400°F) followed by slow cooling to reduce internal stresses created during welding or machining. .
- Aging: Heating at relatively low temperatures (e.g. 720°C to 780°C / 1320°F to 1435°F) to strengthen its structure.
- Quench and Temper: This method is not usually used for SS309.
Characteristic
Characteristic
- High temperature resistance: SS 309 has excellent high temperature resistance and can work at high temperatures up to 980°C (1800°F).
- Excellent corrosion resistance: At high temperatures, SS 309 has good oxidation and corrosion resistance, and is suitable for use in oxidizing and corrosive environments.
- Good mechanical properties: SS 309 has good strength and toughness and can maintain good mechanical properties at high temperatures.
- Thermal shock resistance: The material has a strong tolerance to rapid temperature changes and can resist thermal shock damage.
- Good welding performance: SS 309 can be connected by a variety of welding methods, including arc welding, argon arc welding, etc., and has good mechanical properties after welding.

Packing
Packing
Our packaging is designed to provide maximum protection and minimize the risk of damage during shipping.
- Quality Control: Each tube undergoes a rigorous quality check before packaging to ensure it meets our high standards and specifications.
- Protective Packaging: Tubes are wrapped with protective materials such as polyethylene or kraft paper to prevent surface damage and contamination. To protect the ends of the tubes from dents and deformation, we use high-quality end caps and gaskets to prevent movement within the package.
- Secure Packaging: Tubes are strapped and secured with durable straps to prevent movement during shipping. We use sturdy wooden or metal pallets for added stability.
- Labels and Documentation: Each package is clearly labeled with product details, including size, quantity and part number, as well as handling instructions to ensure proper handling. All necessary documentation, including certificates of compliance and shipping invoices, are included with the shipment.
- Custom Packaging Solutions: We provide custom packaging solutions based on your specific requirements, including special sizes or conditions.
