VALVES & VALVE ACCESSORIES
If you were to do a chemical analysis of ductile iron, this is what you would normally find:
Carbon 3.2 – 3.60%
Silicon 2.2 – 2.8%
Manganese 0.1 – 0.2%
Magnesium 0.03 – 0.04%
Phosphorus 0.005 – 0.04%
Sulfur 0.005 – 0.02%
Copper <= 0.40%
To improve the strength of ductile iron, additional tin or copper can be added. To improve corrosion resistance, copper, nickel, or chromium can replace anywhere from 15-30% of the iron.
Common Ductile Iron Grades
While there are many different ductile iron specifications, foundries routinely offer 3 common grades;
