Here is the link to my explanation about Al31FP being made in India:

Read the entire threads after this as many people had many questions to ask and they have been answered in the thread.
You were part of this thread xxxxxxxxxxxxx xxxxxxxxxxxxxx xxxxxxxx How many times should anyone tell the same thing again and again?
About why SCB is not used in Kaveri, I have again told that Rhenium is the reason. SCB has 3 generations. The first generation does not need Rhenium but the second and third generation needs rhenium. Al31FP definitely uses 1st gen SCB or DS blades. The first and second generation DS don't require rhenium. The second generation DSB also performs better than first generation SCB. More has been discussed in this forum itself. I will give the thread for it:

Even when AMCA is to be made, it will be made with 2nd generation DS with some compromise on engine life and TWR instead of using 2nd or 3rd generation SCB which will be hard to make and can be subject to embargoes during war. 100-110kN engines are used even in older planes like F15 which uses PW100 without any rhenium. So, some compromise of TWR in return for high quantity manufacturing is definitely welcome step.
Manufacturing under license from raw material is called ToT! As long as manufacturing is done in India, it is ToT. ToT does not mean that Russia should teach Indians metallurgy course! And engine metallurgy came to artillery thread because you poked the topic of metallurgy.
