Previous material forging 42CrMo4V 100mm
Transport cost for 4 segments is much cheaper than one forged part with a diameter of 3.850mm!
Steel properties machining (drilling, milling) perfect. Very high tolerances needed. No problems with inner stresses.
Bad availability, long delivery time for forging part and internal toothing
50% cost reduction, 25% saving in weight
Hardox 450, 75mm have been used in this wear part due to lack of material. It is dough recommended to use strenx 700, a structural steel with a guaranteed yield strength and impact toughness.
