Ingasetshenziswa njenge-carbon raiser (Recarburizer) ukukhiqiza insimbi esezingeni eliphezulu, insimbi ehlanganisiwe kanye ne-alloy. Ingasetshenziswa futhi epulasitikini kanye nerabha njengesithasiselo. Ingasetshenziswa njenge-carbon raiser (Recarburizer) ukukhiqiza insimbi ehlanganisiwe, insimbi ehlanganisiwe kanye ne-alloy.
