one of my client is asking for heat treatment for all cold forming component irrespective of fiber elongation i don't know why?

is the shell rolling is also considered as forming process,
no dought if the fiber elongation exceed as per UCS 79 we required to carry out the stress releving, but only the rolling process required SR as per the client requirment,

i think it is not a Forming process,
anyone can guide me.

Thanks
