high temp MT

Any special requirments (other than EHS) to do MT at high surface temperatures (max. 500 deg. celsius).
Does anybody performed such kind of MT?

Regards and thanks in advance,

Ovidiu M. IUGA

You are talking of near Curie Temperatures if not above them. The feasibility and the sensitivity needs to be established.

For one of the job upto 600 deg C MT has been carried out, and sensitivity check shall be done in same tempreture.
This was done in intermediate weld for reactor regenerator in higher wall thickness.
