ASTM B522 Class II vs. SAE-AISI H24 Steel
ASTM B522 class II belongs to the otherwise unclassified metals classification, while SAE-AISI H24 steel belongs to the iron alloys. There are 15 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.
For each property being compared, the top bar is ASTM B522 class II and the bottom bar is SAE-AISI H24 steel.
