Hardened SAE-AISI F1 vs. Hardened SAE-AISI T1
Both hardened SAE-AISI F1 and hardened SAE-AISI T1 are iron alloys. Both are furnished in the hardened (H) condition. They have 78% of their average alloy composition in common. There are 23 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.
For each property being compared, the top bar is hardened SAE-AISI F1 and the bottom bar is hardened SAE-AISI T1.
