EN 1.6571 Steel vs. ASTM Grade LCA Steel

Both EN 1.6571 steel and ASTM grade LCA steel are iron alloys. They have a very high 97% of their average alloy composition in common. There are 24 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 EN 1.6571 steel and the bottom bar is ASTM grade LCA steel.
