ABS vs. SAE-AISI M42 Steel

ABS and SAE-AISI M42 steel belong to fundamentally different material chemistries. ABS is a polymeric material, while SAE-AISI M42 steel is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 9 material properties with values for both materials. Properties with values for just one material (22, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is ABS and the bottom bar is SAE-AISI M42 steel.
