OVERVIEW SPECIFICATIONS AND TECHNICAL INFORMATION

See Stainless Steel Tolerances

Stainless Sheet/Plate 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.
