Stainless Round Welded Tubes
Stainless Steel tubing generally produced in grades 304, 304-L, 316, 316-L. Other grades lower alloys or higher alloys can be produced but subject to prior discussions and arrangements.
Tubing under this specificatin (ASTM A554) covers welded tubing for mechanical & structural applications where appearance, mechanical properties, or corrosion resistance is needed. Some of the applications are e.g food & beverage industry (equipments), automotive industry, high speed trains, sports & fitness equipments, furniture, medical industry (general application), construction & building industries etc.
Sizes: Available from 9.53 mm OD - 406.40 mm OD. Wall Thickess: From 0.50 mm to 8.0 mm.
Lengths: 6000 mm Long. (Specific Lengths sizes can be supplied to save costs - Discuss with sales office).
Delivery Lead-times - Generally 45 - 70 Days. Short delivery lead times can be organised.

Most Common Grades tubes produced to is: Stainless Grades 304, 304-L, 316, 316-L.
*Any other Grades shall be subject to prior discussions & arrangement. Minimum order quantities may apply where by the starting flat product material may have to be specially ordered on flat products mill for production followed by tube mill/producer to manufacture.
* Any special requirments and or project requirments - please contact our sales office for assistance.
Please contact our sales office for any reference requirment.
Generally all tubes are supplied packed in Steel Crates , Wooden Crates or Bundle Packaging (cheaper option, but prone to damage if not handled from producer to end delivery point). Heavier wall tubing can be shipped loose, bundled or in secured lifts. Any special packaging requirments can be arranged subject to prior agreement. Below are couple of common packaging methods tubes supplied by SSM.
