Hardened AISI 416 vs. Hardened SAE-AISI H11
Both hardened AISI 416 and hardened SAE-AISI H11 are iron alloys. Both are furnished in the hardened (H) condition. They have a moderately high 92% of their average alloy composition in common. There are 24 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.
For each property being compared, the top bar is hardened AISI 416 and the bottom bar is hardened SAE-AISI H11.
