 EMI1.1 
 



   Den Gegenstand der Erfindung bilden durch Versticken härtbare Stahl- und Gusseisenlegierungen, die ausser den für Nitrierstahl- und Nitriergusseisenlegierungen bekannten Legierungskomponenten noch einen erhöhten Gehalt an mindestens einem der Elemente Phosphor oder Schwefel aufweisen. Als Aus- 
 EMI1.2 
 den besonderen Vorteil aus, dass sie besonders leicht bearbeitbar sind und trotzdem beim Härten durch   Verstieken   eine sehr grosse Härte annehmen. 



   PATENT-ANSPRÜCHE :
1. Durch Versticken härtbare Stahl- und Gusseisenlegierungen, dadurch gekennzeichnet, dass sie ausser den für Nitrierstahl- und Nitriergusseisenlegierungen bekannten Legierungskomponenten noch einen erhöhten Gehalt an mindestens einem der Elemente Phosphor oder Schwefel aufweisen.

 EMI1.1
 



   The subject matter of the invention is formed by embroidering hardenable steel and cast iron alloys which, in addition to the alloy components known for nitriding steel and nitriding cast iron alloys, also have an increased content of at least one of the elements phosphorus or sulfur. As an exit
 EMI1.2
 have the particular advantage that they are particularly easy to work with and nevertheless become very hard when hardened by reinforcing them.



   PATENT CLAIMS:
1. Steel and cast iron alloys hardenable by stitching, characterized in that, in addition to the alloy components known for nitriding steel and nitriding cast iron alloys, they also have an increased content of at least one of the elements phosphorus or sulfur.
