Annealed SAE-AISI S5 vs. EN 1.7386 +I Steel

Both annealed SAE-AISI S5 and EN 1.7386 +I steel are iron alloys. Both are furnished in the annealed condition. They have a moderately high 91% of their average alloy composition in common. There are 31 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 annealed SAE-AISI S5 and the bottom bar is EN 1.7386 +I steel.
