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, 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.
Density of Ductile Cast Iron is 7300 kg/m 3. Example: Density. Calculate the height of a cube made of Ductile Cast Iron, which weighs one metric ton. Solution: Density is defined as the mass per unit volume. It is mathematically defined as mass divided by volume: ρ = m/V
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.
4 lut 2023 · Ductile iron, also known as nodular cast iron or spheroidal graphite iron, is an alloy made from melted pig iron. It contains higher amounts of carbon than grey cast iron but lower amounts than steel.
Ductile irons belongs to the cast iron family. As the name suggests they are more ductile than most cast irons and have similar properties to grey irons i.e. good hardness, wear and corrosion resistance. Tensile and yield strengths vary widely with different microstructures.
Properties of Ductile Cast Iron – ASTM A536 – 60-40-18. Ductile iron is stronger and more shock resistant than gray iron. Ductile iron has mechanical characteristics approaching those of steel, while it retains high fluidity when molten and lower melting point.
