    Multipurpose 304 Stainless Steel Round Tubes

    Image of Product. Front orientation. Stainless Steel. 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.
    Seamless—Stronger than welded shapes. They have a smooth, uninterrupted surface without stress points from seams. They’re also easy to clean.

    Highly Corrosion-Resistant 316 Stainless Steel Round Tubes

    Image of Product. Front orientation. Stainless Steel. Highly Corrosion-Resistant 316 Stainless Steel Round Tubes.
    Fabricate frames, machine enclosures, railing bases, and other components that hold up in highly corrosive environments. One of the most corrosion-resistant types of stainless steel, 316 stands up to the harshest chemicals, including bleach, chlorine, and phosphoric acid. It’s similar in strength and temperature resistance to 304 but is better suited for demanding marine and chemical-processing environments. Use these tubes 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.
    316/316L Stainless Steel—Dual certified to meet both 316 and 316L requirements. The low carbon content makes this stainless steel easy to weld while maintaining strength and corrosion resistance.
    Seamless—Stronger than welded shapes. They have a smooth, uninterrupted surface without stress points from seams. They’re also easy to clean.
