329 Duplex Temper Embrittlement
329 Duplex Temper Embrittlement
(OP)
I have a 1.5" thick piece of equipment made of 329 Duplex (old duplex grade, approximately 70% ferrite). We experience metal loss in isolated areas (cutting due to slurry) and weld repair these areas. The manufacturer does not recommend weld repairing the material more than 3 times, as they believe more than 3 repairs will cause temper embrittlement. I have not been able to find any literature relating the number of welds to probability of temper embrittlement. Does anyone have any advice they could offer on this matter?
Thank you.
Thank you.

If I can find the TTT curve for 329 I'll add it later.
