EN 1.4123 +A Steel vs. Annealed ASTM F15
Both EN 1.4123 +A steel and annealed ASTM F15 are iron alloys. Both are furnished in the annealed condition. They have 54% of their average alloy composition in common. There are 29 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.
For each property being compared, the top bar is EN 1.4123 +A steel and the bottom bar is annealed ASTM F15.
