Hello Everyone,
I am working in one of the hydro power in Bhutan, we are using two different plates, i.e. ASTM 517 and ASTM 537. Both the plates are using inside the excavated tunnel. Here, i am looking forward for your guidance at what temperature should we maintain for PRE-HEAT....
many many thanks in advance for your support.

Sonam, Bhutan

Follow the WPS requirements.

Preheat is a function of the carbon equivalency, degree of restraint, and thickness. So, a little more information is in order before an answer is possible.
