8620 Cold Drawn Alloy Steel - Rounds
8620 Cold Drawn Alloy Steel
These are "triple alloy" carburizing steels. The nickel imparts good toughness and ductility, and the chromium and molybdenum contribute increased hardness penetration and wear. They are readily carburized, and the well-balanced alloy content permits hardening to produce a strong, tough core and high case hardness. They have excellent machinability and respond well to polishing operations. 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.
In the leaded analysis, machinability is improved without the sacrifice of other desirable properties, with the exception that the use of this material is not recommended for applications over 400°F since at elevated temperature ductility is low.
Stock Lengths 10' to 12'
