Stainless Steel Rectangular Tube 304/304L

Type 304/304L stainless steel, or 18-8 as it is sometimes called, combines remarkable resistance to many corrosive environments with mechanical properties similar to most structural steels. It is non-magnetic in the annealed condition and not hardenable by heat treatment. Its strength can be improved by cold work. Type 304/304L or the low Carbon version (.03 max) of 304/304L should be used when welding is required.




Used in clean room equipment, dairy, beverage, food processing equipment, architectural trim and moderately stressed structural components.
