R05400 Tantalum vs. AWS E309H

R05400 tantalum belongs to the otherwise unclassified metals classification, while AWS E309H belongs to the iron alloys. There are 17 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 R05400 tantalum and the bottom bar is AWS E309H.
