Abstract

The present invention relates to a compound body comprising cemented carbide and steel with a carbon content corresponding to a carbon equivalent Ceq=wt-% C+0.3(wt-% Si+wt-% P) of from about 0.1 to about 0.85 wt-%. The body is particularly useful for earth moving tools e.g. dredge cutter heads.
