ACI-ASTM CA6NM Steel vs. ASTM A356 Grade 2

Both ACI-ASTM CA6NM steel and ASTM A356 grade 2 are iron alloys. Both are furnished in the heat treated (HT) condition. They have 83% 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 ACI-ASTM CA6NM steel and the bottom bar is ASTM A356 grade 2.
