EN 1.5024 +A Steel vs. Annealed SAE-AISI A9

Both EN 1.5024 +A steel and annealed SAE-AISI A9 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 30 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 EN 1.5024 +A steel and the bottom bar is annealed SAE-AISI A9.
