| Abstract: | New lower_alloy air quenching bainite ductile iron grinding of tesearching and producing, have high hardness, better impact toughness, better impact wear-resistance propreties, and the imput for machinery and production cost have been reduced. It is known from the comparison with other materials that wear resistance test, service life of new lower-alloy air quenching bainite ductile iron grinding was 1.8 times higher than that of medium manganese ductile iron, and that is basic to act for high chromium cast iron. It is very valued. |
