Austenitic Nodular Cast Iron vs. ASTM B631 Class B
Austenitic nodular cast iron belongs to the iron alloys classification, while ASTM B631 class B belongs to the otherwise unclassified metals. There are 12 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.
For each property being compared, the top bar is austenitic nodular cast iron and the bottom bar is ASTM B631 class B.
