Holding time normalising of P/T 22 after welding
Holding time normalising of P/T 22 after welding
(OP)
We have been asked to perform mechanical tests of welded joints in P/T22 (2.25Cr 1Mo) which shall be normalised and tempered after welding. The normalising treatment shall be done at 920-940 degree Centigrade according to requirement from our client, but how long holding time shall I choose for weld samples of 20 and 25 mm thickness respectively? I do not want to risk any grain growth.

Anyone else out there with experience of normlaising and tempering 2.25Cr1Mo welds?
