Annealed SAE-AISI H25 vs. Annealed Type 2 Magnetic Alloy
Both annealed SAE-AISI H25 and annealed Type 2 magnetic alloy are iron alloys. Both are furnished in the annealed condition. They have 52% of their average alloy composition in common. There are 19 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 SAE-AISI H25 and the bottom bar is annealed Type 2 magnetic alloy.
