ASTM A36 Carbon Steel vs. EN 1.4823 Stainless Steel

Both ASTM A36 carbon steel and EN 1.4823 stainless steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 66% of their average alloy composition in common. 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 ASTM A36 carbon steel and the bottom bar is EN 1.4823 stainless steel.
