Grade Ti-Pd18 Titanium vs. SAE-AISI T2 Steel

Grade Ti-Pd18 titanium belongs to the titanium alloys classification, while SAE-AISI T2 steel belongs to the iron alloys. There are 20 material properties with values for both materials. Properties with values for just one material (12, 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 grade Ti-Pd18 titanium and the bottom bar is SAE-AISI T2 steel.
