Multipurpose 304 Stainless Steel Round Tubes
 |
Create frames, machine enclosures, railing bases, and other components that hold up in corrosive environments. Made of the most common stainless steel, these 304 stainless steel round tubes are designed for structural and ornamental applications that require strength, rigidity, and aesthetics. They should not be used for pressure containment and fluid handling. Compared to rectangular tubing, they resist twisting better and bend more uniformly.
These tubes maintain corrosion resistance in temperatures up to 1500° F.
304/304L Stainless Steel—Dual certified, choose 304/304L whether you need 304, 304L, or an alloy that captures the benefits of both. Low carbon content improves weldability while maintaining corrosion resistance and strength.
Welded—The common choice for most structural applications. These shapes are formed from a strip that’s welded along the length, so their strength may vary slightly at the seam under extreme loads.
