Was waiting to go to work and saw your post.
Didn't have the slightest idea what you were referring to so I did a google search and found that the difference is (TP347H is coarse grain ) and (TP347HFG (FG) Fine Grain)

I think the ER347 is ok. 347H+347H the filler metal is 347.
You can see the AWS D1.6.
The chemical element and component of TP347HFG is the Same as TP347H(347H). Only the process of produce changed so that the Grain of the steel is changed.

Use TIG (GTAW) with small heat input.
The interpass Temp. not exceed 150℃.

Only for your information.
