AISI 309S stainless steel plate is a low-carbon version of AISI 309, specifically designed to enhance weldability and reduce carbide precipitation. It belongs to the austenitic stainless steel family, known for its superior resistance to high temperatures and excellent corrosion resistance. With a chemical composition including 23–25% chromium and 12–15% nickel, AISI 309S offers remarkable performance in extreme environments.
Key Features:
-
High-Temperature Resistance: reducing environments at temperatures up to 1000–1100°C.
-
Corrosion Resistance
-
Low Carbon Content
-
Good Mechanical Properties
-
Ease of Fabrication
Common Applications:
- Industrial Furnaces: Used in furnace components such as heat exchangers, burners, and oven linings.
- Heat Treatment Equipment: Retorts, muffles, and annealing boxes.
- Petrochemical Industry: Equipment exposed to high temperatures and corrosive gases.
- Power Plants: Heat shields and other components in boilers and turbines.
- Automotive and Aerospace: Exhaust systems and parts exposed to high temperatures.
Benefits:
- Long service life in extreme environments.
- Resistance to scaling and thermal shock.
- Reduced risk of intergranular corrosion due to low carbon content.
