Austenitizing heat treatment required for forgings UG-6 1

[ZGZtanker]

In UG-6 ASME VIII, Div. 1, Edition 2013 some extra requirements have been included for SA-105 forgings to be used as pressure vessel shells. These requirements include an austenitizing heat treatment.

According to what I have read, those treatments were the metal temperature is taken above critical temperature provoking the steel to austenitize should be considered austenitizing heat treatments, in particular annealing and normalizing.

Can somebody confirm me whether this is right?

Thank in advance for your help and best regards.

Yes. Austenitizing treatment in the code means heating the steel to a minimum temperature that results in the total formation of austenite phase in anticipation of either air cooling (normalizing), or quench assist or full quenching and subsequent tempering.
