While lead is often added to steel alloys, it is actually not an alloying element itself. When added to steel, lead does not join with the carbon, iron, and other elements.

While lead is often added to steel alloys, it is actually not an alloying element itself. When added to steel, lead does not join with the carbon, iron, and other elements. Lead is actually not soluble in steel. Rather, lead remains in the steel in the form of inclusions. Lead also has almost no impact on the mechanical properties of the steel, but improves the machinability of the steel because it acts as a lubricant between the cutting tool and the steel. Welding steel with lead additions almost always results in cracks and is not recommended.
Lead is added to steels that will undergo machining but not welding. AISI grades of steel that contain lead typically have an “L” designation. Common alloys include 11L18 and 12L14.
Pb has no apparent effect on the yield strength, tensile strength, reduction of area, elongation, and impact strength of steel. In creep resisting, alloy steels very small amounts of Pb can be harmful. Pb is only added to steels for improving machinability. Pb improves the machinability of high-speeRead more

Pb is only added to steels for improving machinability. Pb improves the machinability of high-speed steels at low and moderate cutting speeds for tools. Alloying with medium carbon steel with Pb improves the cutting speeds around 30 % and when the cutting speeds remain the same, it improves the tool life by 3 to 5 times.
