[MW:34063] SA 765 Grade II ( Normalize + Temper)

Dear Expert,

Kindly advice 
for subjected material I want to qualify PQR P1G2 ( normalize) to P1G2 ( normalize + temper) for impact application.

As lead time for forging SA 765 gr 2 is quite high I want to perform tempering on plate SA516 gr 70 (Normalize) to simulate actual condition of N+ T before welding.

Kindly  advice soaking time calculation for tempring cycle  @ 670 deg cel.
Plate thick 50 mm
