ACI-ASTM CA40 Steel vs. ACI-ASTM CB30 Steel

Both ACI-ASTM CA40 steel and ACI-ASTM CB30 steel are iron alloys. Both are furnished in the heat treated (HT) condition. They have a moderately high 92% of their average alloy composition in common. There are 29 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CA40 steel and the bottom bar is ACI-ASTM CB30 steel.
