Improvement of ball bearing fatigue life by reducing segregation and proeutectoid cementite

$15.00

Recent trends show that in manufacturing ball bearing steels, the ingot casting process is replaced with the continuous casting process. However, the fatigue life of ball bearing manufactured by this process is not satisfactory due to central segregation and the resulting proeutectoid cementite formation in the central region of wire rod.
