Stainless steel AISI 309 is a high-performance austenitic alloy designed for extreme temperature applications. With its elevated chromium and nickel content, it provides excellent resistance to oxidation, thermal shock and mechanical stress up to 1000°C, making it ideal for industrial furnaces and metallurgical processing.

Offered in coils, flattened sheets and custom slit strips, AISI 309 guarantees long-term stability, reduced deformation and outstanding resistance where traditional stainless steels cannot perform reliably.
