What is your Question?
1. Do you want to calculate? or
2. Do you need the value?
 
Allowable stress value are provide i the Tables for ASME I, VIII, in ASME II and in the Tables in B31.1 and B31.3.
 
For reference, per B31.3, the Sa of A105 in terms of temperature are:

65 Deg-C: 156 MPa
100 Deg-C: 151 MPa
150 Deg-C: 146 MPa
 
You're supposed to be an engineer right?.

Regards
 
You extrapolate between the two nearest temperatures in a straight line

So about 152 MPa

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
 
so, As much as increase Degree happened decrease stress in tension and we have to consider value of the highest temp than that if not available in table
 
Look up the word "extrapolate"

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
 
Thanks everybody helping me

Finally

X=(93−100)×(156−151)÷(65−100)+151=152Mpa
 
Finally!
