Annealed ASTM F15 vs. Annealed 350 Maraging Steel
Both annealed ASTM F15 and annealed 350 maraging steel are iron alloys. Both are furnished in the annealed condition. They have 84% of their average alloy composition in common. There are 24 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.
For each property being compared, the top bar is annealed ASTM F15 and the bottom bar is annealed 350 maraging steel.
