Duktilguss
Duktilguss, or ductile iron, is a family of cast irons in which graphite occurs as nodules or spheroids rather than flakes. This nodular graphite is achieved by adding small amounts of magnesium or cerium to the molten iron, a process known as nodulizing, often combined with inoculation. The result is a material that retains the castability and good weight of iron but with substantially higher ductility and impact resistance compared with gray cast iron.
Production and microstructure: Ductile iron is produced by pouring molten iron with nodulizing elements into a
Properties: Typical tensile strength ranges from roughly 400 to 1,000 MPa depending on grade; elongation 6–15%
Applications: Used for automotive components such as crankshafts, gears, and valve bodies, as well as pipe fittings,
Standards: European and international standards designate ductile iron as EN-GJS grades, and the American system uses
