3/4-hard AISI 205 vs. 3/4-hard ASTM F15

Both 3/4-hard AISI 205 and 3/4-hard ASTM F15 are iron alloys. Both are furnished in the 3/4-hard temper. They have 55% of their average alloy composition in common. There are 19 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 3/4-hard AISI 205 and the bottom bar is 3/4-hard ASTM F15.
