HAARDMETALSLIDDEL MED HOEJ SLIDSTYRKE OG GOD STYRKE, SAMMENSAT AF HAARDMETAL OG STOEBEJERN

摘要

A metallic body in which great wear resistance is coupled with excellent mechanical strength and toughness is composed of sintered cemented carbide particles in a matrix of graphitic cast iron-base alloy, the content of carbon plus other constituents known to be equivalent to carbon in their influence on the cast iron amounts to 2.5 - 6.0%, preferably 3.5 - 5.0%.
