JIS G3459 Stainless Steel Pipe
JIS G3459 Stainless Steel Pipe
JIS G3459 Stainless Steel Pipe is a Japanese standard for stainless steel pipes used in high-temperature and corrosion-resistant applications. It covers seamless and welded pipes in various grades like SUS304, SUS316, and SUS321. These pipes are available in different outer diameters, wall thicknesses, and lengths, with end finishes such as plain, beveled, or threaded. Surface finishes include pickled, polished, and annealed & pickled. They are widely used in industries like chemical processing, petrochemicals, and food production.
