JIS G3464 Low-Temperature Seamless Carbon Steel Pipes
JIS G3464 Steel Tubes for Low Temperature Service are steel tubes used for exchanging heat at exceptionally low temperatures, such as in heat exchangers and condensers. These tubes are specified by the Japanese industrial standard and are designed to withstand freezing temperatures. The tubes undergo different heat treatments based on their class, including normalizing, tempering, quenching, and tempering. They have specific chemical compositions and mechanical properties, including tensile strength, yield point, and elongation.
