Lead added to this grade increases parts production by some 25% with excellent finish and good tool life. Machining speeds are increased to 145 sfm and there are no adverse effects on properties. Readily carburized, the well balanced alloy content of this grade permits hardening to produce a strong, tough core and high case hardness.
