ACI-ASTM CF10SMnN Steel vs. AISI 418 Stainless Steel

Both ACI-ASTM CF10SMnN steel and AISI 418 stainless steel are iron alloys. Both are furnished in the heat treated (HT) condition. They have 78% of their average alloy composition in common. 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 ACI-ASTM CF10SMnN steel and the bottom bar is AISI 418 stainless steel.
