Hi Jeff
Strictly speaking, if the base metal is not listed in the AWS D1.1 tables, then it you cannot assign it to a "Group". Having said that, if you are building this for a non-USA client, then they may be happy for you to classify the base material, as it is technically the same as a Group II material. I would address this to the client with a technical query, suggesting to classify it as "Group II".
I would also suggest that this type of question should rather be posted on the forum dealing with AWS codes. The AWS experts hang out there!

Niekie
