JIS G3459 SUS304 pipe is a type of Japanese standard, seamless stainless steel pipe made from SUS304 stainless steel, known for its 18% chromium and 8% nickel content, offering good corrosion resistance. The terms annealing and pickled refer to the post-manufacturing heat treatment and surface finish process, respectively: annealing involves a solution treatment to improve mechanical properties, while pickling removes scale and other surface imperfections to create a clean and corrosion-resistant surface. These pipes are widely used in various industries, including petrochemical, food processing, and decoration, due to their durability and ability to withstand both low and high temperatures.
