Abstract
A cemented carbide has a <70 &mgr;m, preferably 10-40 &mgr;m, thick binder phase enriched surface zone containing W and Mo but depleted in cubic carbide. The overall content of Mo in the surface zone is the same as that in the inner portion of the cemented carbide. By alloying the cemented carbide with Mo, the performance has been improved particularly when used for turning at conditions causing intermittent thermal and mechanical load in stainless steel.
