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...
