EN 1.4849 Stainless Steel vs. EN 1.0536 Steel

Both EN 1.4849 stainless steel and EN 1.0536 steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a modest 40% 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 (5, in this case) are not shown.

For each property being compared, the top bar is EN 1.4849 stainless steel and the bottom bar is EN 1.0536 steel.
