Aged 300 Maraging Steel vs. EN 1.4596 +P1400 Steel
Both aged 300 maraging steel and EN 1.4596 +P1400 steel are iron alloys. Both are furnished in the aged (precipitation hardened) condition. They have 79% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.
For each property being compared, the top bar is aged 300 maraging steel and the bottom bar is EN 1.4596 +P1400 steel.
