ASTM Grade 60-42-10 Ductile Cast Iron

ASTM grade 60-42-10 is ductile cast iron in the annealed condition. It has the second lowest strength compared to the other variants of ductile cast iron. The graph bars on the material properties cards below compare ASTM grade 60-42-10 to: cast irons (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
