Notes :
A. Maximum unless otherwise indicated.
B. When silicon is required, the following ranges and limits are commonly specified: 0.10 %, max, 0.10 % to 0.20 %, 0.15 % to 0.35 %, 0.20 % to 0.40 %, or 0.30 % to
0.60 %.
C. Copper can be specified when required as 0.20 % minimum.
D. When lead is required as an added element to a standard steel, a range of 0.15 to 0.35 % inclusive is specified. Such a steel is identified by inserting the letter “L” between
the second and third numerals of the grade designation, for example, 10 L 45. A cast or heat analysis is not determinable when lead is added to the ladle stream.
E. When boron treatment for killed steels is specified, the steels can be expected to contain 0.0005 to 0.003 % boron. If the usual titanium additive is not permitted, the
steels can be expected to contain up to 0.005 % boron.
F. The elements bismuth, calcium, selenium, or tellurium may be added as agreed upon between purchaser and supplier.
G. Unless prohibited by the purchaser, the manganese content may exceed 0.60 % on heat analysis to a maximum of 0.75 %, provided the carbon range on heat analysis
has the minimum and maximum reduced by 0.01 % for each 0.05 % manganese over 0.60 %.

Notes :
A. Silicon may be specified by the purchaser as 0.10 % maximum. The need for 0.10% maximum generally relates to severe cold-formed parts.
B. The purchaser may also require the following maximums: copper 0.30 %; aluminum 0.050 %; oxygen 0.0015 %.
C. These steels can be expected to contain 0.0005 to 0.003 % boron. If the usual titanium additive is not permitted, the steels can be expected to contain up to 0.005 %
boron.
