AISI 440C Stainless Steel vs. EN 2.4951 Nickel

AISI 440C stainless steel belongs to the iron alloys classification, while EN 2.4951 nickel belongs to the nickel alloys. They have a modest 21% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is AISI 440C stainless steel and the bottom bar is EN 2.4951 nickel.
