GGG40 Nodular Cast Iron- TJC STEEL.
GGG40 is one kind of nodular cast iron named in Din standard.
The Chemical Composition of GGG40:
Nodular cast iron is a kind of high strength cast iron material developed in the 1950s. Its comprehensive performance is TJC STEELclose to that of steel. Based on its excellent performance, it has been successfully used to cast some parts with complex forces and high requirements for strength, toughness and wear resistance. Nodular cast iron has been rapidly developed into a very widely used cast iron material, second only to gray cast iron. The so-called "iron instead of steel", mainly refers to ductile iron.
Nodular cast iron is through spheroidization and inoculation treatment to get spherical graphite, effectively improve the mechanicalTJC STEEL properties of cast iron, especially improve the plasticity and toughness, so as to get higher strength than carbon steel.
In addition to iron, the chemical composition of nodular cast iron is usually 3.0 ~ 4.0% carbon content, 1.8 ~ 3.2% silicon TJC STEELcontent, the total amount of manganese, phosphorus, sulfur is not more than 3.0% and an appropriate amount of rare earth, magnesium and other spheroidal elements.
