N08031 Stainless Steel vs. EN 1.8898 Steel

Both N08031 stainless steel and EN 1.8898 steel are iron alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is N08031 stainless steel and the bottom bar is EN 1.8898 steel.
