EN 1.4971 Stainless Steel vs. ASTM Grade LC1 Steel

Both EN 1.4971 stainless steel and ASTM grade LC1 steel are iron alloys. They have a modest 32% 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 (6, in this case) are not shown.

For each property being compared, the top bar is EN 1.4971 stainless steel and the bottom bar is ASTM grade LC1 steel.
