If you are casting water pipes for a municipal project or gear hubs for a tractor, remember:
But casting ductile iron is not the same as casting gray iron. The metallurgy is tighter, the heat treatment is specific, and the "inoculation" process is critical.
Breaking the Mold: A Practical Guide to Casting Ductile Iron (Ductile Pipe & Components)
When you need the corrosion resistance of cast iron but the impact toughness of steel, there is only one solution: Ductile Iron (DI) . Often referred to as nodular cast iron or SG iron , this material has revolutionized the pipe, automotive, and heavy machinery industries.
