Chromium 33 vs. AWS BNi-4
Chromium 33 belongs to the otherwise unclassified metals classification, while AWS BNi-4 belongs to the nickel alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 17 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.
For each property being compared, the top bar is chromium 33 and the bottom bar is AWS BNi-4.
