EN 1.3551 Steel vs. Commercially Pure Zirconium

EN 1.3551 steel belongs to the iron alloys classification, while commercially pure zirconium belongs to the otherwise unclassified metals. There are 16 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.

For each property being compared, the top bar is EN 1.3551 steel and the bottom bar is commercially pure zirconium.
