Hardened SAE-AISI H13 vs. Hardened SAE-AISI P6
Both hardened SAE-AISI H13 and hardened SAE-AISI P6 are iron alloys. Both are furnished in the hardened (H) condition. They have a moderately high 93% of their average alloy composition in common. There are 24 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.
For each property being compared, the top bar is hardened SAE-AISI H13 and the bottom bar is hardened SAE-AISI P6.
