Stainless steel AISI 321 is a titanium-stabilized austenitic alloy designed to withstand high temperatures, thermal cycling and oxidation. Its superior resistance to intergranular corrosion makes it ideal for applications involving continuous heat exposure, such as thermal plants, aerospace components and automotive exhaust systems.

Available in coils, flattened sheets and custom-cut strips, AISI 321 ensures structural stability, excellent formability and reliable performance in environments where standard 304 stainless steel would risk degradation or sensitization.
