Annealed AISI 202 vs. Annealed SAE-AISI M52

Both annealed AISI 202 and annealed SAE-AISI M52 are iron alloys. Both are furnished in the annealed condition. They have 72% of their average alloy composition in common. There are 25 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 AISI 202 and the bottom bar is annealed SAE-AISI M52.
