[MW:12442] Requirement of Solution Annealing for SS DIshed head after forming

Dear All,
 
Greetings.
 
SS Vessel is being fabricated as per construction code - ASME SEC VIII DIV 1
 
SERVICE : SOUR Service
 
Material of Construction  for Dished Head - SA 240 316L, 20 mm Thickness.
 
I  believe stresses will be  induced in the material  during forming and as a result , Sulfide Stress Cracking (SSC) failure may occur during operation.
 
Whether Solution Annealing of SS Dished Head is required after forming?
 
Please give reference of any International Standard.
 
Thanks & Regards
 
Asad Azmi
