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.

Welded round tubes are more economical than seamless tubes.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY 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 sheets, strips, bars, and adhesive-back foil 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. Mirror-like #7 finish is reflective with some visible grain lines. 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.
