Quarter-hard AISI 304L vs. Quarter-hard AISI 316

Both quarter-hard AISI 304L and quarter-hard AISI 316 are iron alloys. Both are furnished in the quarter-hard temper. They have a very high 95% of their average alloy composition in common. There are 35 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is quarter-hard AISI 304L and the bottom bar is quarter-hard AISI 316.
