Multipurpose 304 Stainless Steel Round Tubes

From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.

304/304L Stainless Steel—This dual-certified stainless steel meets both 304 and 304L requirements. Its low carbon content improves weldability while retaining corrosion resistance and strength.

Seamless—These tubes are more corrosion resistant than welded tubes because they don’t have a seam that could potentially introduce impurities.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Highly Corrosion-Resistant 316 Stainless Steel Round Tubes

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 a step up from 304, which has similar strength and temperature performance. Use it in a variety of marine and chemical-processing applications. It maintains its 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.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
