EN 1.3523 +H Steel vs. Hardened SAE-AISI T4
Both EN 1.3523 +H steel and hardened SAE-AISI T4 are iron alloys. Both are furnished in the hardened (H) condition. They have 71% of their average alloy composition in common. There are 22 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 EN 1.3523 +H steel and the bottom bar is hardened SAE-AISI T4.
