N08135 Stainless Steel vs. ASTM A356 Grade 8

Both N08135 stainless steel and ASTM A356 grade 8 are iron alloys. They have a modest 39% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is N08135 stainless steel and the bottom bar is ASTM A356 grade 8.
