# Allowable stress value of A105

## Allowable stress value of A105

(OP)
How Calculate the Allowable stress value Of Flange A105 At 93 Degree (Celcius ) ?

### RE: Allowable stress value of A105

1. Do you want to calculate? or
2. Do you need the value?

### RE: Allowable stress value of A105

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.

### RE: Allowable stress value of A105

(OP)
i need value if possible

### RE: Allowable stress value of A105

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

(OP)
Thanks

### RE: Allowable stress value of A105

You're supposed to be an engineer right?.

Regards

### RE: Allowable stress value of A105

You extrapolate between the two nearest temperatures in a straight line

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

### RE: Allowable stress value of A105

(OP)
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

### RE: Allowable stress value of A105

Look up the word "extrapolate"

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

### RE: Allowable stress value of A105

(OP)
Thanks everybody helping me

Finally

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

### RE: Allowable stress value of A105

Finally!
