ACI-ASTM CE3MN Steel vs. ASTM Grade LC1 Steel

Both ACI-ASTM CE3MN steel and ASTM grade LC1 steel are iron alloys. Both are furnished in the normalized and tempered condition. They have 64% of their average alloy composition in common. There are 29 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 ACI-ASTM CE3MN steel and the bottom bar is ASTM grade LC1 steel.
