Half-hard AISI 304L vs. Half-hard AISI 316N

Both half-hard AISI 304L and half-hard AISI 316N are iron alloys. Both are furnished in the half-hard temper. They have a very high 95% 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 half-hard AISI 304L and the bottom bar is half-hard AISI 316N.
