Stainless Rectangle 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.

The bar measures 0.25 inches in thickness and 1.5 inches in width, made from 321 stainless steel alloy. It is annealed and pickled, produced by hot rolling, and weighs approximately 2.14 pounds per standard length.

Yes, 321 stainless steel offers high strength and excellent resistance to scaling and intergranular corrosion at elevated temperatures, making it ideal for aerospace and defense components such as engine parts and heat exchangers.

Welding is not recommended for this alloy due to the titanium content, which helps resist intergranular corrosion but makes welding less suitable.

Yes, custom cut lengths are available from the warehouse, with options ranging from 12 inches up to 96 inches, all in stock and ready to ship.

Yes, the product is RoHS and REACH compliant, ensuring it meets important environmental and safety standards.
