Home Alloy Steel 8620 Alloy Steel 8620 Grade Summary: Alloy Steel 8620 has nickel imparts good toughness and ductility, chromium and molybdenum contribute increased hardness penetration and wear. It is readily carburized and the well-balanced alloy content permits hardening to produce a strong, tough core and high case hardness. Typical Applications: Because of the fine combination of properties that may be developed, as well as the ease with which it may be processed, this material is ideal for a wide variety of applications.
