Notes:
a. Elements not listed in
this table shall not be intentionally added to the steel without the agreement
of the purchaser, except for finishing the cast. All appropriate measures shall
be taken to prevent the addition from scrap or other materials used in
steelmaking of these elements which may adversely affect the mechanical
properties and usability. The content of Cr + Cu + Mo shall not exceed 0.50%.
b. For nominal thicknesses ≤
40 mm, a minimum nickel content of 0.15% is permitted.
