Specification for 2.25Cr -1Mo-.25V PV steel

Specification for 2.25Cr -1Mo-.25V PV steel

Specification for 2.25Cr -1Mo-.25V PV steel

(OP)
What are the ASTM/ASME specification numbers for 2.25Cr-1Mo-0.25V pressure vessel steel for heavy wall reactors?

RE: Specification for 2.25Cr -1Mo-.25V PV steel

I suppose this is 22V, K31835.
It is covered by ASME SA-336, 541, 542 and 832.
Look them up and which scope covers your product size.
