Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron [1] and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. [2]

Ductile iron, also known as nodular cast iron or nodular iron, is a cast iron alloy with distinctive properties, including impact and fatigue resistance, elongation, and wear resistance. These properties arise from the spheroidal graphite structures within the metal’s microstructure.

Nodular (spheroidal graphite) cast iron. Nodular iron is also called ductile iron. The graphite is present as tiny balls or spheroids. Because the spheroids interrupt the matrix much less than graphite flakes, nodular cast iron has higher strength and toughness than gray cast iron.

2024年1月23日 · The main difference between grey cast iron and nodular cast iron is that grey cast iron has graphite flakes dispersed in its matrix, while nodular cast iron, also known as ductile iron, has graphite nodules.

Ductile iron, an alloy of iron and carbon, is a special type of cast iron having properties comparable to steel. Due to its unique microstructure, ductile iron exhibits high strength, durability, flexibility, and elasticity.

2024年2月19日 · While malleable iron is more ductile than traditional cast iron, it is less ductile compared to ductile iron. With its nodular graphite, ductile iron has a higher degree of ductility, which allows it to stretch, bend, and deform before failing.

Ductile iron, also known as nodular iron or spheroidal graphite iron, is very similar to gray iron in composition, but during solidification the graphite nucleates as spherical particles (nodules) in ductile iron, rather than as flakes.

Nodular cast iron is a material that has found a increasing number of applications in the automotive industry during the last decade. It has a static strength comparable to cast steels and a greater fatigue strength and ductility than grey irons.

Nodular cast iron is a high-strength cast iron material developed in the 1950s. Its comprehensive properties are close to steel. Based on its excellent properties, it has been successfully used to cast some parts with complex stress and high requirements for strength, toughness, and …
