ASTM Grade LCA Steel vs. SAE-AISI 1137 Steel
Both ASTM grade LCA steel and SAE-AISI 1137 steel are iron alloys. They have a very high 99% of their average alloy composition in common. There are 30 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.
For each property being compared, the top bar is ASTM grade LCA steel and the bottom bar is SAE-AISI 1137 steel.
