The addition of zinc, a sacrificial anode, would prevent the iron metal from corroding. According to the table of Standard Reduction Potentials, the standard reduction potential of zinc is about -0.76 volts. The standard reduction potential of iron is about -0.44 volts.
Ductile Iron is a high strength, tough material used in water and wastewater systems in all. 50 states of the United States and in many other areas of the world. Continuous testing and. field experience have brought the production and use of Ductile Iron pipe to maturity. Although Ductile Iron is chemically akin to gray iron of low phosphorous content, there are significant differences. Ductile Iron must have a low sulfur content, requiring a desulfurizing treatment when the base metal is melted in a conventional cupola.
