Full-hard AISI 201 vs. Full-hard AISI 205

Both full-hard AISI 201 and full-hard AISI 205 are iron alloys. Both are furnished in the full-hard temper. They have a moderately high 91% of their average alloy composition in common. There are 29 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is full-hard AISI 201 and the bottom bar is full-hard AISI 205.
