AISI 309H Stainless Steel vs. EN 2.4663 Nickel

AISI 309H stainless steel belongs to the iron alloys classification, while EN 2.4663 nickel belongs to the nickel alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is AISI 309H stainless steel and the bottom bar is EN 2.4663 nickel.
