4140 Annealed Cold Finished Alloy Steels
These are oil-hardening steels of relatively high hardenability. Their chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. These grades are especially suitable for forging because they have self-scaling characteristics. They respond readily to heat treatment and are comparatively easy to machine in the heat treated condition. They resist creep in temperatures up to 1000°F and maintain their properties even after long exposure at these relatively high working temperatures. With a combination of such highly desirable properties as good strength and wear resistance, excellent toughness coupled with good ductility, and the ability to resist stress at elevated temperatures, it is understandable why these are widely used and highly successful alloy steels.
This material is also available as leaded steel. The addition of lead improves machinability without sacrificing 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.
The following specifications are generally applicable for 4140/42 Heat Treated Rounds: ASTM A 193, Grade B7; ASTM A 434, Grades BC and BD.

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.
