8620 is the most widely used carburizing alloy. Its nickel content imparts good toughness and ductility. The chromium and molybdenum increases hardness penetration and wearability. This steel's well balanced alloy content permits hardening to produce a strong, tough core and high case hardness. It machines at 110 sfm and has good welding qualities.
