ASTM A182 Grade F3VCb vs. SAE-AISI 1018 Steel

Both ASTM A182 grade F3VCb and SAE-AISI 1018 steel are iron alloys. They have a very high 95% of their average alloy composition in common. There are 32 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 A182 grade F3VCb and the bottom bar is SAE-AISI 1018 steel.
