Annealed AISI 202 vs. Annealed 200 Maraging Steel

Both annealed AISI 202 and annealed 200 maraging steel are iron alloys. Both are furnished in the annealed condition. They have 73% of their average alloy composition in common. There are 25 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is annealed AISI 202 and the bottom bar is annealed 200 maraging steel.
