ASTM · United States · 23 grades

A666

The designation A666 is carried by 23 different grades. Compare them on the elements that actually differ, then open the one your print means.

Which of the 23 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.
