Hardened AISI 403 vs. Hardened SAE-AISI 52100
Both hardened AISI 403 and hardened SAE-AISI 52100 are iron alloys. Both are furnished in the hardened (H) condition. They have 89% of their average alloy composition in common. There are 26 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 403 and the bottom bar is hardened SAE-AISI 52100.
