The JIS G3459 standard specifies stainless steel pipes (hereinafter referred to as "pipes") for corrosion-resistant, low-temperature, and high-temperature pipes.
SUS304 is one of the steel types in the JIS G3459 standard.
Pipes should be manufactured using seamless processes, automatic arc welding processes, laser welding processes or resistance welding processes.
