ASTM B522 Class II vs. N08926 Stainless Steel

ASTM B522 class II belongs to the otherwise unclassified metals classification, while N08926 stainless steel belongs to the iron alloys. There are 22 material properties with values for both materials. Properties with values for just one material (11, 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 B522 class II and the bottom bar is N08926 stainless steel.
