(OP)
everyone,
Does anyone know what is the difference between adding inlay on 4130 body with SS316 or INC625?
so far i've seen these two inlays being used on wellhead equipment. but i dont know what's the advantage on one with respect to another. from what perspective we could say it's better.
thank you

Advantage of 625: more corrosion resistant; does not require a different alloy for the first layer
The choice is down to what service the material is expected to see and whether 316 can tolerate it.

is there any specific parameter that become edge point on 316 which considered as a limit before we decide to use 625?
i guess its located at environment constraint in general???

Again, like SJones stated, depends on application which one would be better.
