Notes: 1) The contents of any other element intentinally added is to be determined and reported.
2) If the content of soluble aluminum is not less than 0.015 %, the minimum required silicon content does not apply.
3) Columbium and niobium are considered interchangeable names for the same element and both names are acceptable for use in A01 standards.
4) The indicated amount of aluminum, columbium (niobium), and vanadium applies if any such element is used singly.
5) Ca element need not be reported on the mill sheet unless intentionally added.
