AISI 440B Stainless Steel vs. EN 2.4633 Nickel

AISI 440B stainless steel belongs to the iron alloys classification, while EN 2.4633 nickel belongs to the nickel alloys. They have a modest 27% 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 (3, in this case) are not shown.

For each property being compared, the top bar is AISI 440B stainless steel and the bottom bar is EN 2.4633 nickel.
