Inconel 625, Heat Treatment and Hardness
Inconel 625, Heat Treatment and Hardness
(OP)
I have many projects that require Inconel 625 to be weld inlayed into various oilfield equipment (valves, etc). The Inconel is inlayed into 4130 steel and then put through a stress relief cycle of 1175 deg F for 3 hrs. Can anyone tell me the relationship between the said stress relief cycle and the hardness of the Inconel 625? I have read several articles that say that Inconel 625 will precipitate harden during said stress relief cycle.

You really need to limit the Fe and C in the weld overlay.
While it might make it harder it will lower the corrosion resistance a lot.
You can look in 625 data sheets and see if the 1175 x 3hr should have any effect at all.
