Silicon: It is not common practice toproduce
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.
