Stainless Steel 321 Pipes and Tubes are a grade of stainless steel known for their excellent high-temperature strength and resistance to intergranular corrosion. They are part of the austenitic family of stainless steels and are widely used in various applications where both elevated temperature performance and corrosion resistance are essential.

One of the key features of Stainless Steel 321 pipes and tubes is their superior high-temperature strength. These pipes and tubes can withstand elevated temperatures up to 800-900°C (1472-1652°F) without losing their mechanical properties, making them suitable for applications in heat exchangers, furnace parts, and other high-temperature environments.

Stainless Steel 321 also exhibits excellent resistance to intergranular corrosion, which is a type of corrosion that can occur along the grain boundaries of stainless steels. This resistance is achieved through the addition of titanium to the composition, which forms stable carbides and prevents chromium depletion in the grain boundaries during exposure to high temperatures.

The chemical composition of Stainless Steel 321 Pipes and Tubes typically includes around 17-19% chromium, 9-12% nickel, and 0.1-0.3% titanium, along with low carbon content. The low carbon content in these pipes and tubes reduces the risk of sensitization, further enhancing their resistance to intergranular corrosion.

 Stainless Steel 321 Pipes & Tubes

Machining Stainless Steel 321 pipes and tubes can be challenging due to their high strength and work hardening characteristics. Specialized cutting tools and techniques, as well as adequate cooling during machining, are necessary to prevent work hardening and ensure precise fabrication.
