[MW:12172] effect of heat treatment on impact properties & HIC Properties

Dear all,
 
Greetings.
 
consturction code - ASME SEC VIII DIV 1
 
SHELL Material  - SA 516 GR 70N  HIC - 30 MM Thk.  PWHT is required on the Job at 610 deg Ceclcius.( Minimum). MDMT  is -46 Deg Celcius.
as per client Simulation Heatreatment( 3 Cycles ) is required.
 
 
what will be the effect of Simulation heatreatment ( 3 cycles) on IMPACT Properties.
 
also HIC testing shall be done after one cycle OR 3 Cycles.
 
What will be the effect of Simulation heatreatment ( 3 cycles) on HIC.
 
Please suggest.
 
Thanks & Regards
