[MW:10073] SA264- Heat treatment of Cr-Ni Steel clad plate

In general clad plates produced as per SA264 are heat treated as per para 5.2.1 (i.e. either normalizing or normalizing and tempering depending on the base plate), however can anybody clarify the requirement of para 5.2.3 (when it is applied, the application of cold forming or without hot rolling)

 

“5.2.3 When plates are to be cold formed, or when otherwise required by the base metal specification, the purchaser may specify that such plates, following solution annealing, be heat treated for grain refinement of the base metal by normalizing and either air cooled or water quenched as appropriate. In the case of clad plate manufactured without hot rolling, the base metal and alloy cladding components may be heat treated separately as appropriate prior to bonding.”
