ASTM B631 Class B vs. Austenitic Nodular Cast Iron
ASTM B631 class B belongs to the otherwise unclassified metals classification, while austenitic nodular cast iron belongs to the iron alloys. 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 ASTM B631 class B and the bottom bar is austenitic nodular cast iron.
