ASTM · United States · 9 grades

B166

The designation B166 is carried by 9 different grades. Compare them on the elements that actually differ, then open the one your print means.

Which of the 9 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.
