Annealed SAE-AISI 1330 vs. ASTM A387 Grade 22 Class 1

Both annealed SAE-AISI 1330 and ASTM A387 grade 22 class 1 are iron alloys. Both are furnished in the annealed condition. They have a very high 97% of their average alloy composition in common. There are 31 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 annealed SAE-AISI 1330 and the bottom bar is ASTM A387 grade 22 class 1.
