About Stainless Steel
More
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.
Bars with sheared edges are also known as Gauer bar and are sheared from plate.
Welded round tubes are more economical than seamless tubes.
H-bars have larger flange widths and thicknesses than I-beams, so they’re stronger and carry heavier loads, yet also weigh more. I-beams are lighter weight than H-bars, but they're not as strong. Use them when weight is a concern.

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.
