4130 Postheating
4130 Postheating
(OP)
Is post heating mandatory to be done on 4130 material. We are required to meet hardness of 250 Hv10 and every weld would be subjected to PWHT. Thickness range - 0344" - 1.88". Weld consumable - ER100S-G, E101T1-GH4.
If yes then at what temperature and how much time.

The PWHT temperature would be 50 deg F below the original tempering temperature of the 4130 if it was supplied as Q&T or N & T.
