Furthermore, heterogeneous impurity particles (graphite from the carburizing vessel and Fe-Ni-Cr containing particles from the reduction boat scale) are finely divided and distributed.
Higit pa rito, magkakaiba dumi particle (grapayt mula sa carburizing sasakyang-dagat at Fe-Ni-CR na naglalaman ng mga particle mula sa iskala na pagbabawas bangka) ay pino ang hinati at ibinahagi.
