2205/6% MOLY (75/25 SPLIT)

[copelajo]

Does anyone know the SA spec No. or the UNS for material that would be applicable when 2205/6% MOLY (75/25 SPLIT) material is called for. I don't know where to find details or a manufacturer of such a product. Any basic info would be very helpful.

Try UNS S31254. This may be what you are looking for.

254 is a 6% Mo super austenitic grade. And there are a bunch more.
2205 can be either S31803 or S32205, and it is a duplex stainless.

Are you looking for a higher alloy duplex, or a lower alloy austenitic?
The closes real alloys to a mixture of these two would be a superduplex (S32550, S32707, S32750, S32760).

Okay, I received clarification from the design engineers. They are asking for a shell plate with 25% of the circumference to be 6Mo and the remaining 75% to be 2205. The vessel will essentially be split internally by 6Mo plate to partition two different processes.

Thanks to all for your replies, it is always greatly appreciated!
