NIMONIC Alloy 80A is Nickel-Chromium alloy which is precipitation hardenable. It has largely been superseded by Nimonic 90 and Inconel X-750, but because of the low Cobalt content, it is still specified for nuclear applications. Nimonic 80A performs well in applications where high temperature and continuous stress is a significant consideration. Beyond nuclear applications, it is traditionally used in applications such as gas turbines, as well as for exhaust valves in racing engines and spindles and fasteners for the motorsport sector, it is used for gas turbine components (blades, rings and discs), bolts, nuclear boiler tube supports, die casting inserts and cores, and for automobile exhaust valves
Forgings nimonic 80A maeterial shall be manufactured from steel produced by vacuum induction melting 1 electro-slag re-melting {VIM/ESR) or by vacuum induction melting 1 vacuum are re-melting (VIM/VAR) process.
The hot working shall be done in such a way that a uniform fine grained microstructure is achieved.
The NIMONIC 80A forged material shall undergo the following heat treatment:
Solution annealing temperature shall be between 1050 - 1080C for 8 hours followed by air cooling.Stabilization treatment shall be carried out at 850 t 10'C for 24 hours (air cooling) followed by precipitation hardening at 700 t 10'C for 16 hours (air cooling).
The forgings nimonic 80A forged parts shall be free from defects such as cracks, flakes, seams, segregation, non-metallic inclusionsand other defects which may affect the utility of the forgings.

TEST SAMPLES of finished alloy 80A forged rings
A hardness test shail be performed on all rings at two diametrically opposite positions. At least threehardness indents per position are to be made.
The mechanical properties of nimonic 80A forged rings are to be determined at one forging per melt and heat treatment batch. The specimens are to be taken out of a test sample that has undergone an analogous forming process as the ring. The test sample shall be placed by the rings during the whole heat treatment.
Following NDE shall be performed in delivery condition of nimonic 80A forged turbine blade steel:
100% UT- inspection in simple shaped condition according to EN 10228-4 type 3b and 3c (table 2).100% surface crack inspection in delivery condition according to EN 571-1 or to a similar procedure.
Regarding_ the UT- inspection quality class 3 (table 4) according to EN10228-4 shall be applied. The decision limit for loss of back wall echo is 3 dB and for the real reflector length 10mm.
Defects that will be cut during final machining shall be evaluated individually.
Surface crack inspection - All indications shall be recorded and evaluated individually.
The following details shall be furnished in the test certificate of finished nimonic 80A forged steel:
Heat No. , and melting type.
Dimensional inspection
Details of heat treatment cycle followed.
Results of chemical analysis including tramp elements.
Results of mechanical tests, including hardness test. All individual values shall be reported.Results of ultrasonic tests
Results of surface crack examination
Confirmation of the visual inspection
Confirmation of the verification inspection
Results of additional tests called for in the drawing/order.
