Certificates with a traceable lot number are available for these products. Download certificates from ACTIVITY after your order ships.
Multipurpose 304 Stainless Steel
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 contains less carbon than standard 304 for better weldability.
Seamless round tubes are more corrosion resistant than welded tubes because they don’t have a seam that could potentially introduce impurities.

Clear Scratch- and UV-Resistant Cast Acrylic Tubes
- Color: Clear
- Temperature Range: 0° to 150° F
- Tensile Strength: 10,000-11,250 psi (Good)
- Impact Strength: 0.3-0.4 ft.-lbs./in. (Poor)
- Hardness: Rockwell M94-M100 (Hard)
- For Use Outdoors: Yes
- Specifications Met: Made of FDA Listed Material, UL 94HB
Fabricate containers, tanks, and lenses for light fixtures with these scratch- and UV-resistant cast acrylic tubes. Cast acrylic, which is comparable to Lucite and Plexiglas® Acrylic, is easier to machine than extruded acrylic. This material stands up to outdoor use better than polycarbonate and maintains clarity over time.
Clear Scratch- and UV-Resistant Acrylic Tubes
