ASTM A372 Grade L Steel vs. SAE-AISI 1037 Steel

Both ASTM A372 grade L steel and SAE-AISI 1037 steel are iron alloys. They have a very high 97% of their average alloy composition in common. There are 31 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is ASTM A372 grade L steel and the bottom bar is SAE-AISI 1037 steel.
