ASTM B631 Class C vs. Grade 702C Zirconium
Both ASTM B631 class C and grade 702C zirconium are otherwise unclassified metals. There are 12 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 B631 class C and the bottom bar is grade 702C zirconium.
