About Stainless Steel

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.

For technical drawings and 3-D models, click on a part number.

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

Polished Multipurpose 304 Stainless Steel

Polished to either a brushed or mirror-like finish, this material is widely used to fabricate decorative enclosures and industrial workstations. The polished surfaces are covered with a protective peel-off film. 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.

Brushed #4 is often called a satin finish; it’s similar to a #3 finish, except the grain lines are finer. Rectangular and round tubes are polished on the outside.

Corrosion-Resistant 316 Stainless Steel

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications. It maintains its corrosion resistance up to the maximum temperature.

316/316L stainless steel contains less carbon than standard 316 for better weldability.

Tight-Tolerance Hardened 440C Stainless Steel

With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance. 440C is one of the hardest types of stainless steel after heat treating. This material maintains its corrosion resistance in temperatures up to 800° F.

Tubes are also known as precision shim bushing stock. Use them to decrease a shaft diameter or increase a rod diameter. They are sized so that each tube fits into the next larger size to create a telescoping tube.
