Annealed AISI 403 vs. Annealed SAE-AISI H10

Both annealed AISI 403 and annealed SAE-AISI H10 are iron alloys. Both are furnished in the annealed condition. They have a moderately high 91% of their average alloy composition in common. There are 31 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is annealed AISI 403 and the bottom bar is annealed SAE-AISI H10.
