ASTM A544 304L Stainless Steel Tube Polished Outside 180 grits
The 304 / 304L grade of austenitic chromium-nickel stainless steel pipes are the most versatile and widely used steel piping products. Type 304 / 304L stainless steel is a very low carbon steel that exhibits excellent corrosion resistance. Also, it offers superior resistance to intergranular corrosion following welding or stress relieving. Besides, the 304 and 304L type grades exhibit good machinability and excellent weld-ability characteristics with or without filler metals.
Below are the properties of 304 / 304L stainless steel pipes offered by Arch City Steel & Alloy, Inc.:
304 Stainless Steel Pipe is most suited for applications where superior strength and excellent corrosion resistance is required. 304 / 304L stainless steel seamless pipes are widely accepted in food processing, water treatment, petrochemical, diary, and chemical industries for moving fluids and gases. Welded 304 / 304L stainless steelpipe is ideally used for posts, and poles as well as handrails, in exterior and marine applications. 304 / 304L pipes find extensive use in applications requiring welding, machining, grinding, forming, and polishing.
Because of their durable mill finish and interior welded seam, these pipes are widely used for projects that are exposed to chemical, acidic elements, fresh water, and salt water environments.
