Introduction of 304/304L Stainless Steel Pipe

- Oct 18, 2017 -

304/304L stainless steel pipe is a very low carbon "18-8" austenitic chromium-nickel steel with good corrosion resistance and superior resistance to intergranular corrosion following welding or stress relieving. The low carbon content limits the formation of harmful carbides to such an extent that this grade may be safely used for most operations of welded construction, and where the service temperature is limited to 800° F. It is non-magnetic in the annealed condition and not hardenable by heat treatment. Both hardness and tensile strength can be increased by cold working, which may cause slight magnetism. Available in limited sizes of rounds, squares, and rectangles and 304 Stainless Pipe.
