SAE-AISI H24 Steel vs. ASTM B522 Class II
SAE-AISI H24 steel belongs to the iron alloys classification, while ASTM B522 class II belongs to the otherwise unclassified metals. 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 SAE-AISI H24 steel and the bottom bar is ASTM B522 class II.
