304 Stainless steel square tube

Stainless steel 304 is an austenitic grade of stainless steel that contains high nickel content, typically somewhere between 8 and 10.5 percent by weight and a high amount of chromium that comprises approximately 18 to 20 percent by weight. The lower carbon content of grade 304 stainless steel minimizes chromium carbide precipitation from welding and the alloy’s susceptibility to intergranular corrosion.
