Abstract:

The conditions needed for the model to predict the sensitization and the LTS of type 304 stainless steel were investigated by the measurements of the incubation period in the sensitization.
To measure the incubation periods, EPR test was used.
In isothermal heat treatment, the incubation period was observed. But in isothermal heat treatment following the heat treatment at 1113 K for 700 s, the incubation period was not observed. Reactivation ratio Ra was increased as follows.
