N08028 Stainless Steel vs. ASTM A232 Spring Steel
Both N08028 stainless steel and ASTM A232 spring steel are iron alloys. They have a modest 37% 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 (7, in this case) are not shown.
For each property being compared, the top bar is N08028 stainless steel and the bottom bar is ASTM A232 spring steel.
