Our 309s stainless steel coil is a commonly used and widely applied stainless steel material, offering numerous advantages.


  1. High Temperature Resistance: One of the primary advantages of 309S stainless steel is its exceptional resistance to high temperatures. It can withstand temperatures up to 980°C (1800°F) without significant deformation or loss of mechanical properties. This makes it suitable for applications in heat treatment, furnace components, and other high-temperature environments.

  2. Oxidation Resistance: 309S stainless steel exhibits excellent oxidation resistance, making it resistant to scaling and the formation of oxide layers at high temperatures. This property allows it to maintain its structural integrity and performance in oxidizing environments.

  3. Corrosion Resistance: 309S stainless steel offers good resistance to corrosion, particularly in mildly corrosive environments. It can withstand exposure to atmospheric conditions, certain acids, and alkalis, making it suitable for various industrial and chemical applications.

  4. High Strength: 309S stainless steel has high tensile strength and good toughness, providing excellent structural integrity and resistance to deformation. It can withstand heavy loads and is less prone to breakage or failure.
