the heat. All reasonable precautions shall be taken to prevent the addition from scrap or other materials used in manufacture, of such elements which affect
the hardenability, mechanical properties and applicability.
b. For all steels: phosphorus d" 0.030% and sulfur d" 0.030% (see, however, footnote c).
c. By agreement, sulfur may be increased to between 0.050% and 0.100% and Ni may be omitted.
d. This steel may also be supplied in the pre-heated condition with a hardness of approximately 300 HB.
