Stress Values of UNS S32205 Forging SA 182 F60 Not available in ASME
Stress Values of UNS S32205 Forging SA 182 F60 Not available in ASME
(OP)
In one of our equipment UNS S32205 MOC is applicable.
Hence, for forgings we are using SA 182 F60 which is corresponding MOC for UNS S32205.
However, we found that though this MOC is listed in ASME SEC. II PART-A, stress values fo the same are not available in ASME SEC. II PART-D.
For non-standard forgings we tried to search UNS S32205 MOC under SA-965 being ferritic+austenitic steel. However, we found that UNS S32205 MOC, i.e. F60 grade is not available for SA-965.
Now we require information regarding which MOC and stress values should be considered for forgings.

and UNS S32205 is an F51 flange under SA182 if I remember correctly.
so no problem under VIII-1 and II.

F51 is UNS S31803 while F60 is UNS S3220; both of which are generaically known as 2205 duplex. The primary difference is that UNS S32205 has a more restricted (higher end of the range)chemistry for chrome, moly, and nitrogen compared with UNS S31803. All UNS S32205 satisfies UNS S31803 but not the otherway around.

I meant 31803 (as it is raily available as dual certified 32205/31803) is allowed to be used under VIII-1;
so if your purchase orders are set up tactfully (specify dual certified,
or 31803 with additonial requirements (e.g. a min amount of N)), you can also go for an indirect '2205' application.
I think that summarizes the situation of a vessel I know of, made of 2205,
dealt with it, some time ago
