ACI-ASTM CA40 Steel vs. Ferrite
ACI-ASTM CA40 steel and ferrite belong to fundamentally different material chemistries. ACI-ASTM CA40 steel is a metal, while ferrite is a ceramic material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 12 material properties with values for both materials. Properties with values for just one material (26, in this case) are not shown.
For each property being compared, the top bar is ACI-ASTM CA40 steel and the bottom bar is ferrite.
