[MW:3715] P No- 1 Material

 
Dear All,
 
I have an equipment to be installed in sour services.
 
Material – SA 516 Gr. 70 (HIC tested plates), 132 mm thickness.
 
For PWHT the soaking time is 5.30 Hrs as per project specification. Considering one cycle for future site / modification requirement, the total simulation time works out to be 11 Hrs.
 
PWHT Temperature – 620 Deg .C.
 
What would be behavior of material below LOWER TRANSFORMATION TEMPERATURE (P No. 1), against this cycle? (Tensile property, Impact property).
 
All reputed mills are denying for supply with the simulated testing condition (620 DEG C and 11 Hrs. Soaking Time).
 
Regards,
 
JIGNESH R RANA
