GB/T 9124 Pressure and Temperature Rating Table
Thread Content
I compared the rated pressures of 16Mn and 316 at PN160/100℃ as specified in GB/T9124-2010, and found that at PN160/100℃, the rated pressure for 16Mn is 14.85 Mpa, while that for 316 is 16 Mpa. I believe this may be an error in the standard’s formulation; since 16Mn has a higher allowable stress than 316, its rated pressure should be higher at the same temperature. What do you all think?
The data for HG20592 is the opposite: the rated pressure for 16Mn is 160 bar, while that for 316 is 125 bar.
