ASTM A182 Grade F10 vs. R05255 Alloy

ASTM A182 grade F10 belongs to the iron alloys classification, while R05255 alloy belongs to the otherwise unclassified metals. There are 18 material properties with values for both materials. Properties with values for just one material (15, 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 ASTM A182 grade F10 and the bottom bar is R05255 alloy.
