Hi, 

If you heat treated 900°C , then no need to do 610°C.

Hi

PWHT is required for 45 thk, normalizing is separate heat treatment and cant be combined with stress relieving,

Gentlemen,

Is PWHT can be avoided if the welded head (2 piece construction) performs normalizing after forming ?

Head MOC : SA516 Gr 70, 45 mm thk, fabricated by welding the blank in two pieces. 

Complete vessel not required PWHT.

Thanks & Regards
