Procedure for the evaluation of the quality of rolled bearing
radii on steel crankshafts by
• Evaluation of expansion of the rolled area
• Evaluation of deformation of the microstructure
The metallographical evaluation of the rolled area is a device
for establishing an optimum rolling process and provides for
evaluation of rolling according to agreement with the dynamic
test.
Note: Deviations from this test specification
shall be documented on the finished part drawing, after the
reference to this specification.
