All our products are packed, stored, transported according to the international regulation.

The tubes are wrapped with anti-rust paper and steel rings to prevent damage. Identification labels are tagged according to standard specification or customer's instructions. Special packing is available as per customer's requirement.

Plus, ply wooden box are available for special protection. Other kinds of packing can be offered if request.

Basic information

Small diameter 321 stainless steel tubing has substantially better resistance to intergranular corrosion which is corrosion that occurs in between the microstructure---between the grains of different elements that make up the alloy. 321 SS is, therefore, an important material option for tubing products with service cycles in the 800-1500º carbide precipitation range because the life of the product will be extended (relative to other grades of stainless steel).

Features & Applications

321 stainless steel tubing manufactured for high-temperature applications exhibits excellent resistance to fatigue and cracking, making it ideal for applications including:

Select aerospace applications
Exhaust manifolds
Oil and gas/refinery applications
Processing equipment for high-temperature chemicals
Many other high-temperature service applications
Like our other welded and drawn products, small diameter 321 SS tubing is welded from strip stock, plug drawn in coil form, annealed as needed in order to meet customer temper requirements, and offered in straight lengths or coil form.
