But if the material was not fully annealed in the first place the time would be more like 10sec.
The material does not need residual carbides, just to still have non-uniform composition. Even small local composition gradients greatly accelerate the reactions.
And of course if the temperature actually hit 650C then the time would be more like 2 min.

there is a Ferrite content required from 5 to 20FN. will this ferrite content prevent a sensitization of this steel during a PWHT of 2 hours ?
