JIS G3459 SUS304 Annealing and Pickled Stainless Steel Pipe

​​JIS G3459 is a Japanese Industrial Standard for pipe materials.​​ JIS G3459 pipes are suitable for ​​corrosion-resistant applications in both low-temperature and high-temperature environments​​. The ​​JIS G3459 austenitic series stainless steel​​ includes multiple grades, such as ​​304, 304H, 304L, 309​​, and others.

 

​​We provide JIS G3459 SUS304 pipes​​, which are ​​seamless stainless steel pipes compliant with Japanese standards​​, manufactured from ​​SUS304 stainless steel​​ containing ​​18% chromium and 8% nickel​​, offering ​​excellent corrosion resistance​​. ​​Annealing and pickling​​ refer to the ​​post-manufacturing heat treatment and surface treatment processes​​, respectively: ​​Annealing is a solid solution treatment designed to enhance mechanical properties​​, while ​​pickling is used to remove oxide scales and other surface defects, resulting in a clean and corrosion-resistant surface​​. These pipes are ​​widely used in industries such as petrochemicals, food processing, and decoration​​ due to their ​​durability and ability to withstand both low and high temperatures​​.
