Commercially Pure Silver vs. ASTM A387 Grade 22 Steel
Commercially pure silver belongs to the otherwise unclassified metals classification, while ASTM A387 grade 22 steel belongs to the iron alloys. There are 21 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is commercially pure silver and the bottom bar is ASTM A387 grade 22 steel.
