Commercially Pure Silver vs. ASTM Grade HI Steel

Commercially pure silver belongs to the otherwise unclassified metals classification, while ASTM grade HI steel belongs to the iron alloys. There are 20 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is commercially pure silver and the bottom bar is ASTM grade HI steel.
