AISI 445 Stainless Steel vs. EN 2.4816 Nickel

AISI 445 stainless steel belongs to the iron alloys classification, while EN 2.4816 nickel belongs to the nickel alloys. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 31 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is AISI 445 stainless steel and the bottom bar is EN 2.4816 nickel.
