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
