forging minimum thickness limit
(OP)
Hello,
Is there a minimum thickness limit for forging of apart that is less than 2-inch thickness? if yes, why is that.
thanks

And what tolerances you are looking for.
Remember that the heat treatment on these alloys is very critical.

Are we sure we aren't talking about 2mm. Certainly I'm no forging expert but I could see that being tough to control.

For a fatigue or fracture critical component it is common practice to use a forging that is 100% machined on all surfaces. Hot forgings would usually have at least 1/8" material removed from the as-forged surface. So if your final wall thickness is .25" after machining, the as-forged wall thickness would be .50" from the added 1/8" machine stock on both sides.
Castings are not typically used for fatigue or fracture critical applications. However, for applications where fatigue/reliability are less of a concern and cost is important, a casting will usually require less machining, produce less material waste, and allow details such as internal cavities.
