Forging Ti 6-4

Forging Ti 6-4

Forging Ti 6-4

Good Morning,

What are the best business practices for forging Ti-6-4 to aerospace quality?

Is it okay to forge Ti-6-4 in a furnace that is also used to forge Fe based pieces?

The Ti-6-4 is typically forged around 1700F-1775F while our Steel is forged usually above 2200F? I am worried that the leftover scale from the Iron can cause overheating and potentially contaminate the Ti product. I also asked various other forgers but most either forge strictly Ti or they only use the furnace for Ti and Nickel based alloys or alloys forged within the same temperature range but not any carbon or stainless steels.

Thank you

RE: Forging Ti 6-4

We didn't forge, but we did hot work (extrusion).
Separate furnaces, period.
I wouldn't mind running Ni and Ti through the same furnace, but the temps are very different.
If we were on a long campaign for one we would use both furnaces.
If it was Ti we would set both of them low enough.
If it was Ni we would preheat in the Ti furnace (it didn't even run hot enough for Ni).
In the old days it didn't matter because people left a lot of machine stock.
These days with the emphasis on near net shape there is minimal stock and embedded scale would be a huge issue.
