SAE-AISI L3 Steel vs. ASTM Grade LC3 Steel
Both SAE-AISI L3 steel and ASTM grade LC3 steel are iron alloys. They have a very high 96% of their average alloy composition in common. There are 23 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is SAE-AISI L3 steel and the bottom bar is ASTM grade LC3 steel.
