Alloyed carburized steels contain some characterizing elements that confer different characteristics depending on the applications. After machining, carburizing and tempering, usually performed in oil, these steels have high surface hardness characteristics and notable core toughness. The alloy elements (manganese, chromium, nickel, and molybdenum), added individually or in combination with each other, allow the types to be diversified to use the type best suited to specific needs. The temperability increases with the increase of the alloy elements, and therefore it is possible to obtain core transformed structures into increasingly larger pieces. In particular, chromium tends to increase the core hardness, while the nickel improves toughness and resistance to impacts. The complex of alloyed carburized steels available at Rodacciai allows a truly wide range of applications to be covered, for pieces with sizes from small to considerable. Some of these steels are available in the leaded version, which facilitates machining by chip removal.
