S35045 Stainless Steel vs. ASTM Grade LC2 Steel

Both S35045 stainless steel and ASTM grade LC2 steel are iron alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is S35045 stainless steel and the bottom bar is ASTM grade LC2 steel.
