ASTM A217 Cast Steel vs. Reactor Grade Zirconium

ASTM A217 cast steel belongs to the iron alloys classification, while reactor grade zirconium belongs to the otherwise unclassified metals. There are 20 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is ASTM A217 cast steel and the bottom bar is reactor grade zirconium.
