Stainless Steel 304L Seamless Tubes often eliminates the necessity of annealing weldments except for applications specifying stress relief. Stainless Steel 304L Welded Tubes should be used in heavier sections to reduce the occurrence of carbide precipitation in the heat affected region adjacent to the weld pool. Stainless Steel 304L EFW Tubes is useful in applications where good mechanical properties and corrosion resistance are essential. Continuous use of Stainless Steel 304L ERW Tubes in the 425 Degree C – 860 Degree C range is not recommended if subsequent aqueous corrosion resistance is important. Stainless Steel 304L Round Tubes is ideal for a wide variety of home and commercial applications. SS 304L Square Tubes is an even lower carbon version of Stainless Steel 304 Tubes, which means coolants and lubricants are necessary and must be used in large quantities. Weld annealing of Stainless Steel 304L Rectangular Tubes is only necessary in applications where stress loads are excessive.
