Material group 5 Cr - 1/2 mo High alloy material UHA

[abehong]

Hello:

It seems for me that it does not include 5 Gr-1/2 mo ( P5B- Gr 1 ) group material into Table UHA-32. Does it mean that 5 Gr- 1/2 mo group material not consider as high alloy materail , so the requirement as per UHA does not apply for it. Please clarify .

Thanks

Please look at Part UCS of ASME Section VIII, Div 1. This material is not high alloy, it falls under UCS, Table UCS-56.
