Dears,

When i am using A790 S32760 material, i found

for 100 DegC as per B31,3 is 248 Mpa but in c-II it is showing 246,291 Mpa and

for 125 DegC as per B31,3 is 243 Mpa but in C-II it is showing 241,637 Mpa

can i know why the difference in values pick up, any thing i am missing

attached snap of allowable what i mentioned
