EN 1.4805 Stainless Steel vs. EN 1.4865 Stainless Steel

Both EN 1.4805 stainless steel and EN 1.4865 stainless steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 87% of their average alloy composition in common. There are 30 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is EN 1.4805 stainless steel and the bottom bar is EN 1.4865 stainless steel.
