HI

My Piping Material is Duplex 2205 A790 S32205. But i Can't find it on CAESAR II 5.1 Version.For that I have selected the Equivalent Material that is A790 S31803.

Is it Correct?

But doesn't having any Allowable Stress in B31.1 while selecting A790 S31803 and It's having Allowable Values in B31.3.

Can anyone help on this plz...

Thanks Marian

In CAESAR, While am selecting A790 S31803 material for B31.1 code, It's not giving allowable stress.

Isn't applicable to B31.1 code?

Is applicable for B31.1, have a look in the standard, but you need to fill manualy the allowable in the program.
For All Codes in the material data base is not included the allowable, is included only for B31.3.
