ASTM B685 Alloy vs. Austenitic Nodular Cast Iron
ASTM B685 alloy belongs to the otherwise unclassified metals classification, while austenitic nodular cast iron belongs to the iron alloys. There are 15 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is ASTM B685 alloy and the bottom bar is austenitic nodular cast iron.
