Ductile Iron Having Cobalt

Ductile Iron Having Cobalt

Known cast iron alloys have application limits with regard to temperature. A cast iron including cobalt is provided. Through the use of cobalt, an optimal ferritic microstructure is achieved such that with an alloy having silicon 2.0-4.5 wt %, cobalt 0.5-5 wt %, carbon 2.0-4 wt %, molybdenum 0.3-1.4...

Zusammenfassung:Known cast iron alloys have application limits with regard to temperature. A cast iron including cobalt is provided. Through the use of cobalt, an optimal ferritic microstructure is achieved such that with an alloy having silicon 2.0-4.5 wt %, cobalt 0.5-5 wt %, carbon 2.0-4 wt %, molybdenum 0.3-1.48 wt %, manganese 0.5 wt %, nickel 0.5 wt %, the remainder iron, wherein the proportion of silicon, cobalt, and molybdenum is preferably less than 7.5 wt %, the application limits are shifted to high temperatures.
