AWS BVAg-18 vs. Grade M30C Nickel

AWS BVAg-18 belongs to the otherwise unclassified metals classification, while grade M30C nickel belongs to the nickel alloys. They have a modest 30% 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 (13, in this case) are not shown.

For each property being compared, the top bar is AWS BVAg-18 and the bottom bar is grade M30C nickel.
