2.4650 is a nickel, iron, chromium super alloy which is hardened by aging with the addition of a considerable amount of molybdenum, titanium and aluminum elements. 2.4650 is a high performance material and the manufacturing route may include combinations of vacuum induction melting, vacuum arc remelting and ESR for the final application. 2.4650 is typically used for gas turbine engine discs, shafts, rings, housings and gaskets with a maximum service temperature of about 600 ° C. These are the areas of usage in general. The material has high yield strength and creep resistance at temperatures of 600 ° C.
The following methods are admitted for melting 2.4650,NiCo20Cr20MoT forging parts :
- melting by electric air furnace with elaboration of alloy ( EAF & A OD or VO D ) or vacuum melting (VIM ) ;
- re melting under slag ( ES R ) or under vacuum ( VAR ) .
The 2.4650,NiCo20Cr20MoT forged material shall undergo the following heat treatment:
2.4650,NiCo20Cr20MoT can be solution annealed at 1149°C (2100°F) and rapidly cooled by using the water quench method. It can then be precipitation-hardened at 799°C (1470°F) for 24 h, which can be followed by air cooling.
