EN 1.4852 Stainless Steel vs. EN 1.1221 Steel

Both EN 1.4852 stainless steel and EN 1.1221 steel are iron alloys. They have a modest 37% 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 (3, in this case) are not shown.

For each property being compared, the top bar is EN 1.4852 stainless steel and the bottom bar is EN 1.1221 steel.
