ASTM A356 Grade 1 vs. SAE-AISI 1006 Steel

Both ASTM A356 grade 1 and SAE-AISI 1006 steel are iron alloys. Their average alloy composition is basically identical. 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 A356 grade 1 and the bottom bar is SAE-AISI 1006 steel.
