Change of ASME Code Case 2179-9 to 2179-10(SA335 P92) 1

[Newbie2211]

One of my senior engineer asked me to find out the latest data of SA335 P92.
I found out 2179-10 but I can't find out.
I got 2179-9 but I want to find out whether there is any difference between those two.
Is there any change?
Especially, I want to ask about maximum allowable stress.

 

[TGS4]

The allowable stresses at and above 1,050°F (550°C) are reduced:

Table 2 (Changes)
Temperature (°F)     Allowable Stress (ksi)
    1,050               [s]15.7[/s] 15.4
    1,000               [s]12.9[/s] 11.7
    1,150               [s]8.6[/s] 8.3
    1,200               [s]5.6[/s] 5.3

Table 2M (Changes)
Temperature (°C)     Allowable Stress (MPa)
    550                [s]123[/s] 123 (Note 1 was removed)
    575                [s]99.5[/s] 97.5
    600                [s]77.0[/s] 75.0
    625                [s]56.5[/s] 54.3
    650                [s]38.3[/s] 35.8

Thank you for kind answer, TGS4.
But I have one more question.

At Table 2M, You wrote that Note 1 was removed.
But, There isn't Note 1 at 550 Celcius degree.

Does it mean Note 1 was totally removed from Table 2 and 2M?
I mean, 1050 Ferenheit degree and above, 550 Celcius degree and above?
Aren't those values obtained from time-dependent properties?

The redline that I saw showed that Note 1 was removed from the 550°C row of Table 2M only. If it wasn't there in the -9 version, then rest assured that it's not there in the -10 version. But Note 1 remains for the higher temperatures.

Happy to help.
