This post was last edited by Qinghuan·Ruxue on 2020-4-12 09:23. Can 0Gr18Ni9 be used to manufacture large-scale low-temperature storage tanks? What is the allowable stress for 09MnNiDR?

The critical temperature of liquefied petroleum gas is at room temperature; then why are there low-temperature liquefied petroleum gas storage tanks under pressure? Unless it is at atmospheric pressure, if the atmospheric pressure is above -20°C, Q345R is sufficient. Below -20°C, 16MnDR can be considered.

Is it 0Gr18Ni9 or 0Cr18Ni9? It is no problem to use austenitic stainless steel for manufacturing large low-temperature storage tanks.
