Following of 2.4642 forging parts heat treatment nechanical property Delivery condition :
Rm - Tensile strength (MPa) (+AT) 590
Rp0.2 0.2% proof strength (MPa) (+AT) 240
A - Min. elongation at fracture (%) (+AT) 30
MICRO EXAMINATION of 2.4642 forged parts
Micrographic examination shall be performed on specimens taken in the mid-radius and center of the section used for macrographic examination to evaluate carbide distribution,delta phase distribution,grain and banding.The micrographic samples shall be mounted and polished in the longitudinal direction with respect to the billet.Dedicated additional micrographic inspection shall be performed in case of anomalies are observed at the macrographic inspection.
CARBIDES DISTRIBUTION of 2.4642 forging material
The polished and unetched samples will be examined at 50X to evaluate carbide distribution. Carbides shall be well distributed and shall not form heavy stringers.Obtained results shall be submitted for approval before release the billet.
DELTA PHASE DISTRIBUTION of 2.4642 forged parts
The samples shall be inspected after etching at 400X to evaluate delta phase (Ni3Nb) distribution.No segregation of delta phase shall be present.
GRAIN SIZE DISTRIBUTION of 2.4642 forgings
The average grain size shall be ASTM No.5 or finer.Up to 20%of grain as large as (ALA) ASTM No.2 are allowed.
BANDING of2.4642 forged parts
The samples shall be inspected,after etching,at 100X to evaluate grain banding.Banding is not acceptable in presence of grain size variation,between fine and large grain bands,larger than #4 ASTM numbers.
