Half-hard AISI 301L vs. Half-hard AISI 316
Both half-hard AISI 301L and half-hard AISI 316 are iron alloys. Both are furnished in the half-hard temper. They have a moderately high 92% of their average alloy composition in common. There are 33 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
For each property being compared, the top bar is half-hard AISI 301L and the bottom bar is half-hard AISI 316.
