UNS S31803 vs. S32205
UNS S31803 vs. S32205
(OP)
Is there an optimal solution annealing temperature for dual certified 2205 (UNS S31803/S32205) to achieve the 5 ksi higher strength requirements of S32205 found in ASTM A789 and A815? Several datasheets found on-line indicate that a company's S31803 grade has a typical chemistry that mimics the more restrictive S32205, however they refer to the lower mechanical values of the S31803 grade.





RE: UNS S31803 vs. S32205
It isn't an annealing trick. If you are running the restricted 2205 chemistry you will get the strength.
(And by the way the common term 2205 is S32205.)
The spec strengths are minimums. In reality everone is getting higher strengths.
In some cases for Code applications you will need dual certified, since only S30813 is listed in some places. Soon S32205 will be everywhere in the Code and dual cert won't be needed.

You could get wild results if you blow the grain size up too much, or if you have trouble with cooling rates.
