(OP)
Dear Experts,
Please help. why does the ASME SEC 9, in there material list with correspond to P-no (parent number) & group Number, that some materials are not listed. what is the reason why does those material are not included in ASME SEC 9 QW-422
In my case.. Im using ASTM A707 it is not included in list... so it means it is not C-MN carbon Manganese group-as per P1 material.. please enlighten

1. There has been no request by the B&PV community to use this material for B&PV applications.
or
2. The material does not meet the ductility requirements after welding or is not readily weldable because of alloy content.
