ASTM Grade 80-60-03 (ISO 600-3, EN-JS 1060) Ductile Cast Iron
ASTM grade 80-60-03 is ductile cast iron in the as-fabricated (no temper or treatment) condition. 80-60-03 is the ASTM designation for this material. 600-3 is the ISO numeric designation. Additionally, the UNS number is F34100.
The graph bars on the material properties cards below compare ASTM grade 80-60-03 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.
