Stainless Round Bar 321 provides high strength, high temperature capability, and resistance to intergranular corrosion. 321 resists scaling at higher temperatures. Also, the addition of titanium means that welding is not suggested for this alloy. It is typically used in aerospace and defense for engine parts, heat exchangers, missile components, exhaust stacks, rocket engines, manifolds, and more.

This stainless steel 321 round bar is ideal for high strength and high temperature applications such as aerospace and defense engine parts, heat exchangers, missile components, exhaust stacks, rocket engines, and manifolds due to its resistance to intergranular corrosion and scaling.

Welding is not recommended for this 321 alloy because of the titanium addition, which helps resist intergranular corrosion but makes welding unsuitable.
