Serpi sorry, I was mistaken.
Looked more detailed this time.
Parto, sister company of MAPNA which produces fan blades works with below Alloys.
In738LC, In739, In739 (Nickel Base)
FSX414 (Cobalt Base)
GTD111,GTD222 (Nickel Base)
MAPNA Turbine Blade Company - PARTO
Though one detail catch my eye; "Blades and Vanes are
manufactured from NICKEL and COBALT based super alloys "
Maybe you know, Alp Aviation manufactures of stages 2,3,4 & 5 Titanium IBRs.
View attachment 158260
But what i believe is we are only doing the finishing job, blades itselves must have been coming from US as i don't believe they would share the know how of making IBRs from A to Z.
In PARTO's page it says "manufacturing" can we think that alloys themselves coming from abroad and you are processing it ?
Thanks for detailed explanation.
What i'm trying to explain.
Also i'm trying to explain this fact to Turkish users as well.
