Material cert does not reference EN2952
Para 5.1 of QTR says
Raw material employed is corrosion and heat resistant nickel alloy Inconel 718 Solution Heat treated according to AMS5662 (EN2952 chem only) raw material specific. After the heat treatment it is in according to AMS5663
the heat treatment needs to be the EN or within the QTR showing how the AMS HT is the same as the EN HT
The HT is conform to AMS2774 and EN4047 as required on paragraph.3.5.2. See QTR statement ” Parts are manufactured by cold forming. After solution and precipitation heat treatment (per AMS2774 and EN4047
par. 5.3.2) the hardness values in the final condition are the following” on pag. 12.
Material cert does not reference EN2952
ANSWER—> Raw material is per AMS5662 and EN2952 chem only. We are working in order to have raw material certify for EN spec also in the future.
