UNS · United States · 13 grades

K12437

The designation K12437 is carried by 13 different grades. Compare them on the elements that actually differ, then open the one your print means.

Which of the 13 do you want?

This name is carried by several grades. The elements shown are the ones whose values actually differ across the set — the ones that decide the question. Values are the source text verbatim; an em dash means no value on file for that element on that grade, not zero.
