Hi, 
As we have a plate material SA 537 CL1 (45mm thk) with max.carbon equivalent 0.45 %, as per clients specification requirement (CE < 0.42%) ,we shall get the hardness <200 BHN & impact at           (minus)-47 Deg.C ( 27J Avg.) on WELD and HAZ after PWHT.
Kindly suggest us preheating temprature inorder to get above property.
