JIS G3473 STC 370 carbon steel pipe follows JIS G3473-2007 standard, which is a Japanese industrial standard specifically used for the manufacture of cylinder barrels.
JIS G3473 STC 370 seamless steel pipe has high tensile strength and yield strength, and can withstand greater pressure and load. When subjected to impact or external force, it can maintain good structural integrity and is not easy to break. Due to the presence of appropriate amounts of alloying elements, such as chromium and molybdenum, the steel pipe also exhibits good wear resistance and corrosion resistance, and is suitable for a variety of harsh environments.
