Quarter-hard AISI 202 vs. Quarter-hard AISI 316L

Both quarter-hard AISI 202 and quarter-hard AISI 316L are iron alloys. Both are furnished in the quarter-hard temper. They have a moderately high 90% of their average alloy composition in common. There are 33 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is quarter-hard AISI 202 and the bottom bar is quarter-hard AISI 316L.
