Silicon: It is not common practice to produce these steels to specified limits for silicon.

Lead: When required, lead is specified as an added element to a standard steel and is identified by inserting letter “L” between second and third numerals.

NOTE: The chemical ranges and limits shown are subject to the check analysis tolerance shown in the A.I.S.I. Manual for Alloy, Carbon and HSLA Steels.
